Abstract:
The Kepler mission discovered 2842 exoplanet candidates with 2yr of
data. We provide updates to the Kepler planet candidate sample based
upon 3yr (Q1-Q12) of data. Through a series of tests to exclude
false-positives, primarily caused by eclipsing binary stars and
instrumental systematics, 855 additional planetary candidates have
been discovered, bringing the total number known to 3697. We provide
revised transit parameters and accompanying posterior distributions
based on a Markov Chain Monte Carlo algorithm for the cumulative
catalog of Kepler Objects of Interest. There are now 130 candidates in
the cumulative catalog that receive less than twice the flux the Earth
receives and more than 1100 have a radius less than 1.5R⊕.
There are now a dozen candidates meeting both criteria, roughly
doubling the number of candidate Earth analogs. A majority of
planetary candidates have a high probability of being bonafide
planets, however, there are populations of likely false-positives. We
discuss and suggest additional cuts that can be easily applied to the
catalog to produce a set of planetary candidates with good fidelity.
Description:
We began with the transit-event candidate list from Tenenbaum et al.
(2013ApJS..206....5T 2013ApJS..206....5T) based on a wavelet, adaptive matched filter to
search 192313 Kepler targets for periodic drops in flux indicative of
a transiting planet. Detections are known as Threshold Crossing Events
(TCEs). Tenenbaum et al. utilized three years of Kepler photometric
observations (Q1-Q12) -the same data span employed by this study based
on SOC 8.3 as part of Data Release 21 (Thompson S. E., Christiansen J.
L., Jenkins J. M. et al. Kepler (KSCI-19061-001)).
