      Tabby, have you considered the option of working with Breakthrough Lsten from Breakthrough Initiative of Yuri Milner or maybe with public project SETI@home in Berkeley? The point is to process the change in luminosity with the help of their algorithms and try to identify some kind of regular dependence, the drop down from normal distributions of values for natural processes. For any artificial object, even under construction or collapsing, they have to attend. Yeah, what about "metallicness" of this star? I mean, that's what: https://www.aanda.org/articles/aa/abs/2017/07/aa30761-17/aa30761-17.html. Can there even be formed of large solid objects?

      @Robo Durden interesting thoughts! Yes, I believe that measurements indicate the dip is complex in shape. I urge you to post on https://www.reddit.com/r/KIC8462852/ for a wider audience!

      @Tabby, Hey, the "Elsie" dip www.wherestheflux.com/single-post/2017/05/30/Dip-update-5n is very interesting :-)

      Either your error bars are totally wrong or there is a nearly periodic dimming on top of the approx. 5 day dipping !!!

      1. the main object (causing the 5 day dip) is either as large as the star itself or only crossing it's edge, because otherwise there should be a plateau at 0.98% while the object is traversing the star ?

      2. the additional dipping can not be a moon of the object because it would have to orbit the object in 1-2 hours and the the dipping event would be sinusoidal and not a approx. 1 day event in which the magnitude rises by 0.01% within 1-2 hours.

      We should note, that this 1 day periodicity hints a system error here on earth !

      If not and if your error calculation is correct, it is really cool to start imagining what kind of object could create such observable periodic dipping events of just a few hours. It must be big but also must be super light to move that fast.

      And if that phenomenon only happend with the dip it is bound to the main object, so orbiting it ?

      I guess, the 5 days width of the main dip and the absolute dimming of the magnitude should yield a relation of the the objects-mass , star-orbit and object-velocity. This might already confirm if the main object can be a normal planet, etc.

      All this would be a great popular lecture on astro physics: how much one can learn from simply measuring one value over time !

      http://www.spektrum.de/news/tabbys-stern-flackert-wohl-von-selbst/1433453
      ...they think the star is flickering "from itself" when switching between two different states, as the object seams to be near a critical level between those states.

      Here I would like to develop the idea of the possibility of the existence of natural objects, which under certain conditions can be observed as artifacts of extraterrestrial civilizations. I propose next to call them Pseudo-Dysonian Objects (PDO).
      As a model consider a young star system to the formation of planets, consisting of the central star and gas-dust protoplanetary disk. Now assume that the protoplanetary disk is abnormally rich in complex hydrocarbons, able to form long polymer chains. Why? While this question is set aside.
      Now, dust particles in the disk are covered by a layer of hydrocarbons, forming long polymer chains, which in areas of high concentration interlock with each other. Under the action of corpuscular light and heat radiation of the stars on the inner edge of the protoplanetary disk is their polymerization and sintering the longest film of dust hydrocarbon material. The term "film" here means that the thickness of the object is extremely small compared to other dimensions. In fact, the material is soft and its thickness is considerable, but the polymerization is terminated as soon as the rays of the star are significantly attenuated the previously formed layers. Thus formed PDO can have significant dimensions and has the properties of the solar sail. Under the influence of light radiation of stars it is oriented with the plane perpendicular to the radiation flux, but can rotate around the axis perpendicular to the plane. Its maximum dimensions in the General case determined by the strength of the material to rupture at a given temperature and mechanical stresses from the combined action of light pressure (the magnitude of the second order of smallness) and the centrifugal forces during the rotation.
      The formation of PDO possible in a fairly narrow area. Somewhat closer to the star will start the softening of the polymers and then evaporation of hydrocarbons a little further – the temperature is insufficient for polymerization. In addition, this region should not be planetesimals by gravitational perturbations which PDO can stick together in clumps, forming planetesimals same. Interestingly, in this period of great inner (closest to the star) of the surface of PDO may occur synthesis of a large number of complex organic molecules.
      In the future, PDO, although their reflectivity and small – the surface is fairly dark due to inclusions of dust – moving under pressure of the luminous flux from the star as the solar sail, gradually moving away from the star, with their orbits in the General case can be non-Keplerian, and are the natural analogues of Dyson Dots*.
      In the formation of large planets from a protoplanetary disk, the inner space of the star system would soon be "purged" them from the PDO – and accumulated on the surface of the PDO complex organics can be a material for further development on the surface of planets simplest biological forms.
      On remote orbits at low temperatures, the PDO can persist as long as the nucleus of the comet, although the material is gradually degraded under the action of galactic radiation, and the large PDO, especially rapidly rotating around the axis perpendicular to the plane, over time, disintegrate into fragments. Also under the action of even a weak gravitational interaction, they can concentrate in large clusters.
      Interesting possible the observed pattern. PDO can close the disk stars, and distant from it – is quite noticeable, and should be watched as a potential exoplanets by the transit method (but not by the method of radial velocities!), getting thus in a list of unconfirmed exoplanets.
      PDO in young stellar systems close to the star orbits are significantly heated, and accordingly, not only to block the disk of the star in the optical range, but emit in the infrared part of the spectrum as the classic elements of a hypothetical Dyson sphere. However, this introduces a contradiction: the young age of the star system does not fit well with the hypothesis of a highly developed civilization, which leads to even less plausible the hypothesis of a large sailing fleet of the aliens – the less likely that dust rich protoplanetary disk is not the most suitable place for solar sails, as it contributes to their rapid deterioration and destruction.
      Cold PDO on remote orbits (the more large heterogeneous clusters), as noted above, even more able to block seeing the light from stars, but it is almost never emit in the infrared range, because their temperature is low. As far as is known, a similar pattern is observed in Tabby (WTF) star.
      Remains unresolved the question posed earlier about the presence of a large number of complex hydrocarbons in the young protoplanetary disk. About Tabby star no such data. In young stellar systems, this phenomenon can probably be detected by spectral analysis.
      Most likely, on the outskirts of the Solar system objects, similar to the PDO, no – otherwise it would have if the observations were periodically noted the overlap of their stars. So the probability of this phenomenon seems rare, but not zero.
      I would like to further consider this possibility in relation to the Tabby star.

      Here's another thought, about ekzoplanetoy objects, somewhere else on the level of feeling. Many technical devices have natural counterparts, this is based on the bionics, for example. And are there any natural objects like Dyson Dots? For example, there is a protoplanetary disk (as in EPIC 204278916), and it is saturated with heavy hydrocarbons. Under the effect of radiation from the star they polymerized and "baked" in a flat film (opaque due to the inclusion of dust particles) on a notional inner surface of the disk (closer to the star). But do not stick together in clumps under the influence of gravity, because uniformly loaded on the surface pressure of the luminous flux and taut as a natural solar sails. Is this complete nonsense? Or can we simulate?

      Hello. I'm hoping some of you super smart people could help. I have (I think) identified a precise pattern in the intervals of objects occulting Boyajian's Star. Given I went 4 decimal places, it seems unlikely to be coincidental (see work below):

      Here are the Kepler numbers for the isolated triple dips:

      Starting on day 1537:

      Peak of Dip 1 happened at 1537.8924; Peak of Dip 2 happened at 1540.3853; Peak of Dip 3 happened at 1542.8782 The duration between Dip 1 and 2 is exactly 2.4929 days The duration between Dip 2 and 3 is exactly 2.4929 days

      Starting on day 1204:

      Peak of Dip 1 happened at 1204.2125; Peak of Dip 2 happened at 1205.8881; Peak of Dip 3 happened at 1207.5637 The duration between Dip 1 and 2 is exactly 1.6756 days The duration between Dip 2 and 3 is exactly 1.6756 days

      (dip2 - dip1) = (dip3 - dip2)

      See image of above two triple dips here: http://imgur.com/a/pGo8y

      It would be great to have serious attention from professionals to look at and confirm this. For those willing to help, here is the file source: http://www.wherestheflux.com/public.

      Hi Tabetha,
      I checked the funder's list and found out that while i pledged $50, my name appears (spelled correctly:)) on the $25 pledgers.
      I think I know how it happend as initially I pledged $25 but after your last minute call I doubled my pledge to $50 so maybe the system did not update this doubling.
      Anyhow it would be nice if you could move me to the list of $50 pledgers.
      P.S.- I look forward to seeing some (hopefully) interesting results of the continued observation project, Keep up the great work !

      @Keith Henson: What an interesting exercise! We could only wonder what such a light sail might be used to do. To answer your question: "If this did happen, is there a way to tell the difference between an F type and an artificially warmed up cooler type?" An optical spectrum of the star (which we have) tells us the star's atmospheric properties, and hence its classification as an F type star. Light shades couldn't change that, and would only dim this overall output.

      Keith Henson on July 22, 2016

      Hi Tabetha

      One of your fans here.

      Decades ago Eric Drexler of Nanotech fame and I figured out how to change the spectral type a star. It involved hanging a hemisphere of light sails over the north and south of a star with just enough space along the ecliptic to illuminate the planets. Now why aliens would *want* to change the spectral type of their star is anyone's guess, but they could. For that matter, we could if we wanted.

      If this did happen, is there a way to tell the difference between an F type and an artificially warmed up cooler type?

      If the edge of one of the hemispheres is a bit uneven and rotating, i.e, partly in orbit, from our vantage we could be seeing the edge of it drifting over our line of sight to the star.

      Another idea is that we are staring into a giant alien version of a James Webb type space telescope. That design radiates heat out of the plane of the local ecliptic.

      If there are aliens out there, and they go the speed up route humans could . . .

      https://web.archive.org/web/20121130232045/http://hplusmagazine.com/2012/04/12/transhumanism-and-the-human-expansion-into-space-a-conflict-with-physics/

      Then the distance to other stars may just be too daunting for them to come and visit.
