KIC 2581316 - Unlisted Planet Candidate or Eclipsing Binary?


Planet Hunters forum Talk members flagged this transit for KIC 2581316 around May of 2011. There are now four observed transits through quarter 9 in the released Kepler data set. It appears that this transit was originally flagged as a false positive, but no longer appears on that list. The star has a magnitude of 11.69.

Here is Kian Jek's comment:
"From the profile it looks like a classic planetary transit, and may not be an EB after all - rapid drop offs, with a clustering of data points at a U-shaped bottom. Unfortunately we don't know the radius of the star."

Here is Daryll Lacourse's comment on Keppixseries below:
"July released target pixel files for KIC 2581316; the transits/eclipses seem visible and included within the large optimal aperture masks in each case. Contamination does not seem to be involved."
