Hunt for Trojan planets in the Kepler data

A Systematic Search for Trojan Planets in the Kepler data
http://arxiv.org/abs/1307.7161

No convincing candidates found down to ~1 Earth radius. Also considers the possibility that apparently single KOIs with TTVs could be in mutually-inclined Trojan configurations - while testable for some systems e.g. KOI-103.01 again there is nothing definitive.

Meanwhile there also seems to be an additional transiting candidate at KOI-2393 in the Earth-size range, period about 6 times shorter than the previously-known candidate.
