16 New Transiting Planet Candidates from Kepler Q1-Q6 Data    [PDF]

Xu Huang, Gáspár Á. Bakos, Joel D. Hartman
We have performed an extensive search for planet candidates in the publicly available Kepler Long Cadence data from quarters Q1 through Q6. The search method consists of initial de-trending of the data, applying the trend filtering algorithm, searching for transit signals with the Box Least Squares fitting method in two frequency domains, visual inspection of the potential transit candidates, and in-depth analysis of the shortlisted candidates. In this paper we present 16 new periodic planet candidates and 8 single transit events.The periods of these planet candidates vary from ~0.968 day to ~440 day. Nine of the planet candidates have radii smaller than 3 Rearth. We also report seven newly identified false positives---systems that look like transiting planets, but are probably due to blended eclipsing binaries.
