Update: New additions since beginning of summer have been checked and compiled. The current total is now 246 new candidates (as of 1/2/12) from the original 41 so far that have not appeared on any official list. Discovery credits to be added soon.

These EBs are currently not included in any of the following lists:

Prsa's Kepler EB list (http://astro4.ast.villanova.edu/aprsa/kepler/)

Coughlin et al's list (http://arxiv.org/abs/1007.4295)

Borucki et al February Data Release (http://arxiv.org/abs/1102.0541)

Planet Hunters' EB candidate list (http://talk.planethunters.org/collections/CPHS0001lu/discussions/DPH1003dk3)

Planet Hunters' PC list (http://talk.planethunters.org/collections/CPHS0001ls/discussions/DPH1003dk1)

Periodicity checked by looking up MAST data by Kepler ID, using periodograms and folded light curves for short-period, or scanning through Q1 and Q2 FITS files to identify timings for primary and secondary eclipses for longer period EBs. A check for background star contamination also performed and noted where applicable.

The actual list is now accessible here, as part of the Unlisted EBs collection.

I was trying to compile a list of potential candidates discovered by Planet Hunters that may have been overlooked. I started compiling one for planet candidates but it was the case that so many turned out to be EBs that I decided to put this up first.

I went through a few collections to vet for periodicity and plausibility using Q2 data to confirm, but IANAA (I am not an astrophysicist) so the candidates on this list needs to be checked. OCs and ELVs are sometimes hard to distinguish from each other, and from short-period intrinsic pulsators.

Some of them, especially the long-periodicity detached EBs even need Q3 data to confirm.

This is by no means comprehensive and I probably missed out quite a few; so if you have any candidates that you think were overlooked and not here, just add to this discussion. I will also update this list when I can.

If you have any other comments whether the ones here should stay or go off this list, please add a note here as well.

To see who provided original commentary and speculation on the characteristics of each potential EB, please go to the talk page for each star.

Let me put a shout out here for Goryus, HeadAroundU, CTidwell3, ggccg, zoo3hans and Tom128 who did a splendid job collecting and IDing many potential EBs. I helped myself to some of their hard work. john.philip, kbaskins, michaelshopkins, greg_78_FR, bernix73, nighthawk_black and thaulmielx appear many times in the comments. jmrasor who helped with FFT and periodogram analysis. Wokkels for identifying many of the EBs, especially some of the trickier ones. ShropshireMan for providing a datamined master list of Kepler variables. Thanks to arralen, constovich and EDG for helping me bounce ideas around. Pauldrye for originating the term shutter-effect and making me LMAO with his dry wit. If I have missed anybody else out, the fault is mine.

@zoo3hans

AKA KID 6362386, it's on Prsa's list.

http://talk.planethunters.org/objects/APH10146503 try this

http://talk.planethunters.org/objects/APH10150242 binary or just pulsating with complex amplitude modulation?

http://talk.planethunters.org/objects/APH10071214 probably just pulsating...

http://talk.planethunters.org/objects/APH10071664 looks like a good one

http://talk.planethunters.org/objects/APH10081139

http://talk.planethunters.org/objects/APH10019051

http://talk.planethunters.org/objects/APH10092438 is this binary? very harmonic, if this can be one ( http://talk.planethunters.org/objects/APH10123948 )

http://talk.planethunters.org/objects/APH10078663 ?????

http://talk.planethunters.org/objects/APH23076946

http://talk.planethunters.org/objects/APH21129188 interesting

http://talk.planethunters.org/objects/APH23064161 fresh one, I think it's a binary

Here is another one

APH21392246

  • you have to zoom in quite a bit, there's a shutter effect with ~0.5 period

  • there's no APH10392246, so it's been "gained" in Q2

a look on this one

APH23071960

small step during 0,3 day.

APH10006865

D10,3 to 10,5.
