A SYSTEMATIC SEARCH FOR TRANSITING PLANETS IN THE K2 DATA (2015, background): “In fact, the follow-up process to try to rule out such astrophysical false positives is a large portion of the effort that goes into a transit survey (e.g., O’Donovan et al. 2006; Almenara et al. 2009; Poleski et al. 2010).”
ON THE LOW FALSE POSITIVE PROBABILITIES OF KEPLER PLANET CANDIDATES (2011, background): “At first this appears to somewhat contradict Almenara et al. (2009), who reported 6 planets and 25 diluted binaries among CoRoT’s “solved candidates” (ignoring the “undiluted binary” category, as we are not considering that possibility for Kepler ).”
SOPHIE velocimetry of Kepler transit candidates VII. A false-positive rate of 35% for Kepler close-in giant candidates (2012, background): “…al. 2006) show that these false positives are mainly caused by undiluted eclipsing binaries with a low-mass stellar companion (Moutou et al. 2008; Almenara et al. 2009) or diluted eclipsing binaries (so-called Based on observations made with SOPHIE on the 1.93-m telescope at Observatoire de…”
