Amateur Kepler Observatory Identifies 15 Possible TTV Planet Candidates

Planet Hunters forum Talk member troyw has developed a novel program for analyzing Kepler light curves called the Amateur Kepler Observatory (AKO). Here is his introductory comment:

"AKO is web based software continually developed for viewing data from the Kepler Space Telescope. AKO is currently limited to long cadence data. AKO reads the data entered into its database and sorts that data in a specific way. The data is sorted into rows and columns, and each data point is represented by a grey colored box, usually 3 pixels by 3 pixels, on a dynamically generated image."

More detailed information here.

Troy has created a new thread on the Planet Hunters Science board called " Planetary Transit Timing Variation (TTV). The black horizontal lines are indications of a planet transit. One of the unique aspects of AKO is looking for Transit Timing Variations (TTVs) in the Kepler data for exoplanets. This is performed by stacking multiple quarters of the star's light curves.

Well done troyw. It would be very useful to have a comprehensive alphanumeric list of all TTVs (KIDs, KOIs, ect) found with AKO by everyone posted on this thread for crosschecking and updating. The TTVs currently are posted in multiple different threads. It's impossible to keep track. It would be nice to have one thread as "TTV Central".

Yeah, that's sort of the idea, although I'd rather keep stellar TTVs separate from the planetary ones. I'll make another thread when I get the time for the stellar TTV candidates.
