Planet Hunters Talk member Dolorous Edd has identified an unlisted 1.53 relative Earth size planet transiting KIC 6587796. The transit was also flagged by Planet Hunters member Steve-1759 in Q4 Though the transit is listed in the Kepler Transit Crossing Event Archive for 2012, it has not been characterized as a planet transit.
Kian Jek:
Very nice find. Even though it's in the TCE list (Tenenbaum et al 2012), it's not characterized as a planet. After detrending and cleaning up, the transits are very clear.
Eyeballing the phased curve (folded at 33.4203) reveals that it has a very nice planetary profile. A modeling run with TAP gives these:
The parameters I obtained from TAP are slightly different from the TCE. Depth of 340 ppm, duration 4.93 hr, impact parameter of 0.044, a=0.197AU, Rp=1.53xRE (yes, Super Earth!) and a Teq of 537K.
UKIRT 1'x1' image looks good - but could there be something at 2 o'clock?
Folded stacked pixel centroids plot doesn't show any APOs.
