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-...
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...

Retrieval of Precise Radial Velocities from Near-Infrared High Resolution Spectra of Low Mass Stars
...
Given that low-mass stars have intrinsically low luminosities at optical wavelengths and a propensity for stellar activity, it is advantageous for radial velocity (RV) surveys of these objects to use near-infrared (NIR) wavelengths. In this work we describe and test a novel RV extraction pipeline dedicated to retrieving RVs from low mass stars usin...
A High-Precision NIR Survey for RV Variable Low-Mass Stars
...
We present the results of a precise near-infrared (NIR) radial velocity (RV) survey of 32 low-mass stars with spectral types K2-M4 using CSHELL at the NASA IRTF in the $K$-band with an isotopologue methane gas cell to achieve wavelength calibration and a novel iterative RV extraction method. We surveyed 14 members of young ($\approx$ 25-150 Myr) mo...
Planetary Candidates Observed by V: Planet Sample from Q1-Q12 (36 Months)
...Published in arXiv preprint arXiv:1501.07286
The Kepler mission discovered 2842 exoplanet candidates with 2 years of data. We provide updates to the Kepler planet candidate sample based upon 3 years (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 disco...

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...
Planet Population Statistics With Kepler Q1-Q16: Stellar Effective Temperature Dependence
...
We explore extrasolar planet population statistics and the dependence of planet occurrence rates on stellar effective temperature from analysis of the Kepler Q1-Q16 planet candidate sample. The analysis takes advantage of the recent work on the Q1-Q16 Kepler planet candidate sample, extensive Monte-Carlo transit signal injection and recovery tests ...
Dissecting Kepler s Objects of Interest: Complete Uniform MCMC modeling of the KOI Database
...
We present an analysis of the Kepler Object of Interest Catalogue based on complete MCMC modeling to provide posterior distributions. We show how planet- candidates, eclipsing binaries, background blends and false-alarms assemble into populations based on fundamental transit parameters such as transit duration and depth. Our work identifies regions...
