Blend Analysis of HATNet Transit Candidates
Harvard-Smithsonian CfA, 60 Garden St., Cambridge, MA, USA
Candidate transiting planet systems discovered by wide-ﬁeld groundbased surveys must go through an intensive follow-up procedure to distinguish the true transiting planets from the much more common false positives. Especially pernicious are conﬁgurations of three or more stars which produce radial velocity and light curves that are similar to those of single stars transited by a planet. In this contribution we describe the methods used by the HATNet team to reject these blends, giving a few illustrative examples.
