That's right, another fucking KIC 8462852 thread, but this time it's different. Instead of just fapping about what we'd if we contact ayy lmao's let's do something useful, let's search for more alien megastructures!
Go to http://www.planethunters.org/ and start searching!
It's the same shit that was used to discover KIC 8462852.
TL;DR let's hunt for ayy lmao's using the internet!
>the thread gets populated by /x/ and ayylmaologists
Shhhhh.... These are containment threads.
It keeps /x/ busy while the real /sci/entists are busy discussing why free will can't exist, whether 0.999... = 1, brain uploads, and order of precedence in 6/3*2.
maybe we're seeing a binary star system. See how the intensity increases just before and just after the dip? This could be right before and right after the smaller star transits the main star, at the point where the Rayleigh criterion is too low to distinguish between them and the brightness is combined, then as the small star transits, it ends up blocking more light than it can compensate for. I guess this can happen with a small young star and a large bright supergiant, but it's weird that the second dip blocks more light than the first. The second dip could possibly be a large planet, while the first dip is a small star. I'm referring to your second pic btw >>7624094. There are obviously flaws to this theory that I may have overlooked, I'm not an expert either.
>let's search for more alien megastructures!
There's one in your mothers bed.
>SETI said there could be a preliminary announcement as soon as tomorrow.
Aylmao confirmed. Hopefully they're broadcasting wikipedia unecrypted so we find something useful like zero-point energy and anti-gravity.
The extended quote was to the effect, "We expect to announce toward the end of the week that we found nothing, so the optical and spectral observations can continue to look for a natural explanation."
I know you. I've been in lab groups with you. You sneer at everyone else's contribution while adding nothing. No one ever rats you out because it isn't necessary. The prof and the TAs already know.
>Instructions are clear and comprehensible
>Get this clusterfuck as my first assignment
Here's a sexy beast. An eclipsing binary with an apparent interference geometry, caused by the harmonic between the system's orbital period, and Kepler's observation interval.
Kepler's aperture has a fairly wide view, I think something like 4 arseconds per pixel. So depending on what's around or what is behind any given star, the field is wide enough to catch a lot of noise.
For comparison, here is a 5x5 arcsecond view of a distant galaxy- it has thousands of point sources in it.
So yeah, sometimes Kepler is blurry.
Another hottie. Two obvious planets. The baseline of the star is sharp and constant. The two transits are periodic and symmetrical. Super star.
Just look for transits and hit next afterwards. You can leave comments like #variable or #pulsar or whatever on the strange stars. There's a hintbox that pops up saying what to leave for which patterns after you hit no transit, the major thing to look for is transits though.
How much magnitude change on the left hand vertical scale?
If just a tiny bit, like 1.000 to 0.996, then it's probably starspots. If a lot, like 1.010 to 0.960, then it's a Cepheid variable.
this one's pretty cool. a flare at 8 maybe and a possible transit? duration of dip seems off for transit though.
For one thing, Aichan's period between events of 1500 days allows a calculable orbit of between 3 and 15 AUs. This one: >>7624086 is only 10 days between objects. There's no way to know if it happens again, but applying Tabby's logic, if >>7624086 were periodic on a twice-per-30 day orbit, they would be closer than Mercury to the Sun, so those are some pretty hot ayy lmaos.
Also >>7624086 shows brightening during the second event, which Aichan does not. This is most likely an interaction between two stars meeting for the first time, or playing out some highly elliptical orbital fireworks. Notice the variation induced after day 28. The whole baseline got changed. Aichan returned to the original baseline after both flux dips.
thought on this one?
That's about right tbh.
Here's one of yours.
Yes. Like another star.
This one appears to have a rapid rotation of about 12 hours. That's the high frequency variation of about 0.0025 that defines the baseline. I bet it would look more clear zoomed in. That variation at days 18-22 is only about 1.3%, so it's a small variation, small enough to be starspots or prominences, like we get on the sun at the same magnitude. An eruption of prominences from 18-22 followed by some persistent starspots 22-30 is one way to explain this one.
seeing this a lot (circled in red). seem to be a lot of different interpretations of this kind of event in the comments on these images.
Always look at the vertical axis before even looking at the light curve. That little smudge has a total flux variation between 1.013 and 1.006. Total 0.7% variation. And it's noisy. It's most likely starspots. But it could be a tiny rocky planet.
So do we already have some models for how the Tabby's Star transiting object might look like?
A couple of things I haven't seen answers to:
Has a transiting planet been observed for KIC 8462852 in addition to this weirdness? If not, and we assume for a minute that it is a megastructure, then They Who Built It (TWBI) would have come from a different star system.
What are the closest star systems to KIC 8462852, and do any of them have observable transits? Possible home world of TWBI?
Also, we're looking for radio signals and other forms of communication from KIC 8462852. But what if KIC 8462852 *is* the form of communication? Sort of an interstellar beacon, made from an entire star. Rather than transmit radio or laser, which get noisy and basically useless at these distances.
Yeah, but also about interesting planet hunter specimens in general.
Aichan (KIC 8462852's given name on /sci/) has no observed transiting planets. Also no planets close enough to be emitting in near infrared in any orbit.
Different star system. Yes. I suppose. There is the "both" possibility that Aichan is surrounded by an exocometary ring system, and now that we know comets tend to be rich in organic molecules, including molecular oxygen, it is possible to speculate a form of life that inhabits comets. It is also possible to speculate about a form of life that builds megastructures without an abstracting intelligence. Like bees, ants, or the corals that built the Great Barrier Reef. It could be it's just what they do.
Say they are intelligent, as we define it. How much energy would you spend on a single function stellar lighthouse? It must do something besides just that. In addition to that.
True, it seems to us like an absurd use of time, materials, and energy, but all that is relative. Perhaps making a star beacon is not a big deal, like us building a lighthouse. I'm not saying it's a good theory, just trying to think outside le box a bit. If it's hard to harness enough energy to transmit a "hello" signal for an extended period of time (thousands of years) an orbiting megastructure that could potentially orbit for hundreds of thousands of years if not millions would do the trick nicely.
BSM is just being cautious, as a Man of Science should be. But we are not Men of Science, we are the men who bend the light of the universe through sheer will alone and will shake hands with our ayyys brothers at Aichan.
either that or my ramen is boiling ever and i'm out of red bull. brb.
Its something we never observed before. Remember when pulsar were discovered? Everyone thought it was AYY LMAO.
I respect his cautious stance. I have the same stance. I believe its a new natural phenomenon we haven't observed before. I believe if it was AYY LMAOs then they would have hide their Dyson swarms/spheres to avoid detection from other civilizations. Just like our stealth bombers avoid radar.
I do agree completely- we haven't observed other stars up close at all in this way, so I'm sure there's tons of perfectly natural shit going on that looks insane from our perspective.
I mean, Kepler's prob been looking at Aichan for about 2 years maybe? Is that the data we have now? If one were looking at our solar system in the same way for the same time period, there's a ton of stuff that might be missed.
wuts an eclipsoid binary
do u think its aleins?!?!?!
yeah, the gas giants maybe, but that's only if they're on the right orbital plane to be observed. If they're not, it would look like there ain't shit around our sun. Unless you were able to see a wobble, then you could infer there was something, but that's it....

Discussion on this one here:
Also, a bit technical, but an excellent tool. A calculator for deriving the radius of a transiting planet, to determine if the flux is from a planet or a star. By calculation, if the dip is greater than about 4%, it is almost certainly another star. That is also based on the largest known super gas giants, plus the physics of gravity and fusion, above which certain size, gravity would ignite fusion.
And here is a super duper light curve simulator for eclipsing binaries which really helps to visualize how these data are produced.
For the weirdo >>7624086 , try the preset 29. V442 Cyg, and increase the eccentricity. You get a similar light curve. It turns out one of the pros says the noise in this particular star is reduction error, rather than flaring.
I've tried every variation of a binary system, and can't solve for this curve. The only explanation is three stars and a planet. The total light expands as all three stars come apart, then the first star (star 2) transits star 1 (dip 1), then passes (total light recovers), then the second star (star 3) passes (dip 2), and the transiting planet is in orbit around star 3.
Uhm, excuse me my good sir are you trying to discredit the field of AYYLMAOlogy? I'll have you know I have personally surveyed 300 planets for AYYYLMAO'ns and been involved in numerous secret raids on the reptilian planet of Muhscalydic. I've trained in aaspergerology and nerdcriptics & I'm the most powerful server host in the entire known multiverse, you are nothing to me but a single cell now even worthy of the mars rover SOIL sample [*Gawfawwed chuckle*] My research will end your doubht and probably your ego, oh wait. I swear to LMAOnaise (The mayan god of LMAO incase you didn't know) you think you can just go on the internet and tell lies? what are you NSA? CIA? FBI? S&M? M&M? As we speak I'm contacting my reptillian counterparts on my WoW raid server and we're going to kill your warchief, you're a waste of SPACE [*Autistic laugh that was way to loud*] You don't mess with SIRI.
One other explanation is that two smaller stars are orbiting each other, while they, as a pair, simultaneously orbit the central star. The "planetary" dip is the result of the extremely fortuitous alignment of all three stars in a triple eclipse.
But I would prefer it to be a planet. Planets are always cooler.
>The only explanation is three stars
A regular doubledipping event with three stars? Nope.
A triniary system can exist assuming one of the stars are really far away, to get a regular doubledip that's not possible. The stars would've buttfucked eachother long before planetary formation were possible.
Actually Kepler has found one already. No planets, but a double dip, with p-mode acoustic waves in the red giant. pic related is a scale of the one they found. So it is something already observed, but with no planets.
Look at this curve. I'm thinking it's a glitch. Never seen a straight line like that.
I am convinced that one of the imperative mechanisms of the citizen science project is filtering for people who can perform the task systematically.
The first step pf this system is understanding the vertical axis. I've seen dozens of curves that span the whole screen top to bottom, but the high vertical is 1.0009 and the low is 99.0034. Look again at your exemplar.
There are also "flatline" stars where the top is 1.3055 and the bottom is 0.8622. That's a huge difference.
I think the pros measure our input based on whether we are reading the vertical.
Exciting stuff. Close to an announcement. One or two more days.
Just for fun, we could try to guess the size of the fluctuations (and therefore the vertical scale) based on the apparent signal to noise ratio in the lightcurve he posted. The variation is clearly above the noise level at least, which is why you said it is either starspots or a variable star. To go further than that we'd have to know more about the noise characteristics of Kepler... Probably easier to just look at the vertical axis instead.
>Please tell me why you ignore pilot, astronaut and radar confirmations of UFOs
I find these stories very interesting when I hear about them, but so far no UFO sighting has ever yeilded a prediction or reproducible result that has supported the existence of ayylmaos. Sightings that have been deeply investigated (e.g., ones that were seen and photographed by hundreds or thousands of people) have been debunked. The ones that remain unexplained have not been fully investigated, because they have never repeated in a predictable way, so we can't make any more observations of them to figure out what they are.
I certainly believe that people have seen unexplained lights and even objects in the sky. I do not believe space aliens put them there, because I am not aware of any other evidence that is consistent with the existence of space aliens in our stellar neighborhood. If they existed, there are several kinds of traces I would expect them to leave. It is of course possible that they visit us in some way that is undetectable by our methods, although the fact that people see UFOs with their naked eyes seems to contradict that. Certainly there is nothing strictly scientific we can say about "alien visitations" other than that there is an absence of any evidence that is BEST explained by that idea.
Instead, we talk about blips of light from distant stars, because these are things that can be observed and meausred with objective instruments, and the measurements can be repeated as many times as we like.
this is just the scanning (although they've already started analysing) they'll likely be scouring through it all for a while
>tfw you don't work at SETI to witness the excitement and anticipation first-hand
bumping for any news from the Seti search or any other tidbits.
not really, actually. It depends on the materials used. A solar sail can be only fractions of a millimeter thick. You'd have to assume that a civilization capabale of even seriously thinking about a Dyson sphere/swarm/bubble would have have the materials science needed to make some crazy shit- nanotubes, nanobots, self-replicating systems that use material mined from astroids, etc.
And also, molding whole planets isn't as crazy as it sounds. That's basically just mining and engineering on steroids. Building an orbiting space station or sending a spacecraft out of our solar system would have sounded totally fucking nuts to people 300 years ago. Give us a 1,000 years or so and who knows, man.
I mean, no, something this wouldn't be "convenient", but it certainly doesn't violate and laws of the universe and is something we can conceive of making, even if we don't have the capability (yet).
going by what we know, building the ISS wasn't convenient, which is pretty huge for something humans put together in orbit, but it would be much easier for a technologically more advanced species with space elevators and very advanced propulsion, robotics, materials, etc.
it would not take as much material as an earth-sized planet to build an enormous solar farm or something, maybe if it had the circumference of a gas giant or small star it might take a small moon, also there are plenty of base materials available in asteroids, maybe not enough to construct something as big as a Dyson sphere
there's nothing we know of that says that huge artificial structures can't be constructed though, I think it'd be weirder if none exist in the entire galaxy or universe than if they did [/speculation]
Welcome to /sci/, by the way. Don't let the haters get you down.
>he key to Kepler revitalization lies in its shape. By facing one of Kepler’s six hexagonal edges towards the Sun, the pressure exerted by the sunlight will push on the spacecraft’s body. If Kepler starts to roll slightly in one direction, the light pressure will be become unbalanced, and the spacecraft will be pushed back toward a balanced position. In other words, the sunlight can act as a replacement for Kepler's third reaction wheel!
Then what is it, genius? No one is saying it definitively is a Dyson sphere. Probably a comet swarm. But it sure as shit isn't a transiting planet.
transiting planet curves don't look like that. they don't suddenly drop down. the stars light would gradually decrease as the celestial body slowly occludes it. That graph is fake and gay

I always had this idea that, sometime, perhaps millions of years ago, there was a MASSIVE battle. Thousands and thousands of starship firing laser weapons and hurling aircraft carrier sized projectiles at each other.
Being space and all, the projectiles that didn't hit their target or over penetrated flew off into the cosmos. Most were captured by other star systems or sucked into black holes or whatever you fancy. But one salvo of hundreds of rounds from one of the largest battle cruisers careened off into space, traveling millions of years until it was drawn in by the gravitational pull of a small yellow star with a few planets, one of which had some oceans and was teaming with life.
Basically Earth is destroyed by the remnants of a massive war that happened millions of years ago and hundreds of light years away.
Read as much as you can about what to look for and what some of the more common light curves mean. You're looking for something very specific, not just something "weird". Although "weird" is how we all found KIC8462852, so if it's truly anomalous, mark it and post it in the talk section.
You should read the Science pages first. They are not technical, and describe what is of interest to the pros. They also describe some of the things you will be seeing.
Priority one is transits.
Second is standard candle stars; Cepheids, RRLyrae, Delta Scuti, other variables. Standard candles are important for measuring big distances at the galactic scale.
Third are interesting systems like eclipsing variables.
ALWAYS check the vertical scale first. There are lots of stars whose curves sweep the whole screen, but the top number is like 1.0005 and the bottom is 0.9991. That's less variability than a small sunspot on the sun. Each curve graph is focused differently.
Big flux is almost always more interesting than tiny flux.
I always keep this page open for reference.

"and so I stared into the abyss...and soon the abyss stared back unto me"
I want a video game where we battle intergalactic space whales. Why can't we have that? Give me one good godamned reason. Just one.
This one is interesting for what is happening with its tags. Most of them say "transit" or "transitingplanet" because of the deep dips.And at 1% of total, they are the magnitude that would be expected for a planet.
The giveaway is the bouncing baseline. The additional brightness is not coming from a planet. It's coming from a star. This is an eclipsing binary.
Here's a good example of a nothing burger. This looks like a huge sweeping Long Period Variable (wow! maybe I found a new Mira star!), but a glance at the vertical axis shows the whole change is about 0.45% - similar to what we are getting from region 2243 on our own sun right now:
What do you say, planet hunters? I think this is a gas giant very close in. One of those freaks that theory said could not exist until Kepler found a bunch of them.
Can we model how a transition would look like for KIC8462852 transitions like this:
I mean - how does the object that causes such a sharp dip so deep even look like? Even a hypothetical one? Can it be multiple rings for example?
Yes. And with that orbital period, it is likely a contact binary, where the stars share an envelope, and one consumes some plasma or coronal mass from the other. That's likely the source of the flaring, too. Be neat to have optical imagery of that one.
I saw one yesterday where the vertical went to -475.0. I don't think that's even possible.
You know, is it hypothetically turns out to be real, and there is something alien out there...
Almost the worst part is that, everything will continue as normal, there won't be any great effort to conquer the stars, no massive investment in space programs except perhaps, a couple of new telescopes and an early warning system. And we'll just continue our petty terrestrial bullshit. and focusing on our quarterly stock portfolios.
I wouldn't be too sure about that. Discovering extraterrestrial intelligence (or life) might just change everything. For one, you might consider the things that happen on this dust ball a little more highly not just hoping, but actually knowing that our future lies among the stars and everything depends on how capably we as a species can make that happen. Imagine billions of people gradually arriving at that view.
If I were an alien race in control of a star's brightness, I'd make it do something impossible, and very clearly patterned.
For example, if the structure allowed me to filter light, I'd oscillate between green and purple switching after relative times of 2, 3, 5, 7, 11, 13, 17, 19, etc. all the way to some number that would make the 2 seem like a brief flash by relation (Though the shortest intervals would have to be long enough that the limited speed of light wouldn't make it so that the star would transition before it had fully changed colour, which would take a few seconds perhaps).
Alternatively, have it spent a ratio of Pi:1 time between green and purple.
Mostly green because it's more unusual, but some purple because although less obvious it's still an unnatural colour for a star and very unnatural to have been green only moments ago.
They both occlude the light around %20 intensity. None of them creates a dimming profile like KIC did. The only way to get a sharp spike is if you stretch the graph so fucking hard.
The profile of swelling amplitude, with higher highs and lower lows, is typical of a relatively newly discovered non-radial variable called a Gamma Doradus variable, after the first one discovered. One of the planet hunters keyed me in after I found a similar one. There is a collection in the Zooniverse of about a dozen or so.
so funny, my sides are literally flying to the KIC now... are you retarded?
The SETI optical telescope at Boquet in Panama is observing, as well as the network of pros and amateurs at AAVSO. The plan is to refer any notice of another dimming event to a Big Glass with a spectrometer. I think Wright has an observation plan pre-written and ready to individualize to a specific telescope as soon as anyone sees anything.
One spectrum will answer this pretty decisively. If whatever it is is opaque, then ayy lmao theories live. If we get lines, like hydrogen, sodium, helium, etc., then it's a gas and/or dust cloud. Or cometary debris.
thank you kind sir. here, have a nice kitty
Reminds me of the book End of a Era by Robert Sawyer in which some alien race modified the brightness of several nearby stars creating a pattern that sent a clear message of their existence to the anyone who could see it but never physically reach them just to reassure any other races that exist that they aren't alone in the universe. Humans evolved too late to see that message as those stars burnt out my the late mesozoic.
