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...

Planetary Candidates Observed by Kepler. VII. The First Fully Uniform Catalog Based on The Entire 48 Month Dataset (Q1-Q...

Published in arXiv preprint arXiv:1512.06149

We present the seventh Kepler planet candidate catalog, which is the first to be based on the entire, uniformly processed, 48 month Kepler dataset. This is the first fully automated catalog, employing robotic vetting procedures to uniformly evaluate every periodic signal detected by the Q1-Q17 Data Release 24 (DR24) Kepler pipeline. While we priori...

Terrestrial planet occurrence rates for the Kepler GK dwarf sample

Published in The Astrophysical Journal

We measure planet occurrence rates using the planet candidates discovered by the Q1-Q16 Kepler pipeline search. This study examines planet occurrence rates for the Kepler GK dwarf target sample for planet radii, $0.75\;\ leqslant\; $ $R _ \ rm p $ $\;\ leqslant $2.5$R _ \ oplus $, and orbital periods, $50\;\ leqslant $ $P _ \ mathrm orb $ $\ leqsla...

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...

Semi-weekly monitoring of the performance and attitude of Kepler using a sparse set of targets

The Kepler spacecraft is in a heliocentric Earth-trailing orbit, continuously observing~ 160,000 select stars over~ 115 square degrees of sky using its photometer containing 42 highly sensitive CCDs. The science data from these stars, consisting of~ 6 million pixels at 29.4-minute intervals, is downlinked only every~ 30 days. Additional low- rate X...

Kepler Science Operations Center architecture

We give an overview of the operational concepts and architecture of the Kepler Science Processing Pipeline. Designed, developed, operated, and maintained by the Kepler Science Operations Center (SOC) at NASA Ames Research Center, the Science Processing Pipeline is a central element of the Kepler Ground Data System. The SOC consists of an office at ...
