[201.02] Fraction of Stars With Planets in the Open Cluster NGC 1245

C. J. Burke (The Ohio State University)

We analyze a 19-night photometric search for transiting extrasolar planets in the open cluster NGC 1245 as part of the Survey for Transiting Extrasolar Planets in Stellar Systems (STEPSS) project. Using an automated transit search algorithm with quantitative selection criteria, we find six candidates, none of which are bona fide planetary transits. We characterize the survey detection probability via Monte-Carlo injection and recovery of realistic limb-darkened transits for every star in our sample. This allows us to derive upper limits on the fraction of cluster members with close-in Jupiter-radii companions. We also provide realistic expectations for transit discovery rates from future transit surveys similar to STEPSS.
