Measuring Transit Signal Recovery in the Kepler Pipeline. III. Completeness of the Q1-Q17 DR24 Planet Candidate Catalogu...
...Published in The Astrophysical Journal
With each new version of the Kepler pipeline and resulting planet candidate catalogue, an updated measurement of the underlying planet population can only be recovered with an corresponding measurement of the Kepler pipeline detection efficiency. Here, we present measurements of the sensitivity of the pipeline (version 9.2) used to generate the Q1-...
False positive probabilities for all Kepler objects of interest: 1284 newly validated planets and 428 likely false posit...
Published in The Astrophysical Journal
We present astrophysical false positive probability calculations for every Kepler Object of Interest (KOI)—the first large-scale demonstration of a fully automated transiting planet validation procedure. Out of 7056 KOIs, we determine that 1935 have probabilities
Detection of Potential Transit Signals in 17 Quarters of Kepler Data: Results of the Final Kepler Mission Transiting Pla...
...Published in arXiv preprint arXiv:1604.06140
We present results of the final Kepler Data Processing Pipeline search for transiting planet signals in the full 17-quarter primary mission dataset. The search includes a total of 198,709 stellar targets of which 112,046 were observed in all 17 quarters and 86,663 in fewer than 17 quarters. We report on 17,230 targets for which at least one transit...

How the Sausage is Made: Kepler s False Alarms, False Positives, and Planet Candidates
The Kepler mission has now designated over 7,000 Kepler objects of interest (KOIs), or transit-like signatures, utilizing up to four years of data. The number of potentially habitable planet candidates (PCs) among this sample has risen significantly over time. However, starting with Kepler threshold crossing events (TCEs), there are initially about...

Automatic Classification of Kepler Threshold Crossing Events
...
The Kepler Science Operations Center detects interesting, exoplanet transit-like signals while searching over 211,000 distinct light curves. The mission has produced four catalogs of interesting objects with planet transit-like features known as Kepler Objects of Interest (KOI). The total number of objects with transit-like features identified in t...

Low-Mass Eclipsing Binaries from Kepler: Reaching the Natural Rotation Rates of M and K Dwarfs
An outstanding problem in stellar astrophysics is that the radii of low-mass, main- sequence stars in eclipsing binary systems are consistently 10-15% larger than predicted by stellar models. This inflation is hypothesized to be primarily due to enhanced magnetic activity as a result of their binarity, and thus artificially enhanced rotation rates....
