Secure TTV Mass Measurements: Ten Kepler Exoplanets between 3 and 8 Earth Masses with Diverse Densities and Incident Fluxes
Daniel Jontof-Hutter, Eric B. Ford, Jason F. Rowe +7
We infer dynamical masses in eight multi-planet systems using transit times measured from Kepler's complete dataset, including short-cadence data where available. Of the eighteen d…
Kepler-1647b: the largest and longest-period Kepler transiting circumbinary planet
Veselin B. Kostov, Jerome A. Orosz, William F. Welsh +28
We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest addition to the still-small family of CBPs defies the current trend of known short-period…
The Eccentricity Distribution of Short-Period Planet Candidates Detected by Kepler in Occultation
Megan Shabram, Brice-Olivier Demory, Jessi Cisewski +2
We characterize the eccentricity distribution of a sample of ~50 short-period planet candidates using transit and occultation measurements from NASA's Kepler Mission. First, we eva…
Period Ratio Distribution of Near-Resonant Planets Indicates Planetesimal Scattering
Sourav Chatterjee, Seth O. Krantzler, Eric B. Ford
An intriguing trend among Kepler's multi-planet systems is an overabundance of planet pairs with period ratios just wide of mean motion resonances (MMR) and a dearth of systems jus…
The Ĝ Search for Extraterrestrial Civilizations with Large Energy Supplies. IV. The Signatures and Information Content of Transiting Megastructures
Jason T. Wright, Kimberly M. S. Cartier, Ming Zhao +2
Arnold (2005), Forgan (2013), and Korpela et al. (2015) noted that planet-sized artificial structures could be discovered with Kepler as they transit their host star. We present a…
The mass of the Mars-sized exoplanet Kepler-138 b from transit timing
Daniel Jontof-Hutter, Jason F. Rowe, Jack J. Lissauer +2
Extrasolar planets that pass in front of their host star (transit) cause a temporary decrease in the apparent brightness of the star once per orbit, providing a direct measure of t…
