High-resolution Multi-band Imaging for Validation and Characterization of Small Kepler Planets
Mark E. Everett, Thomas Barclay, David R. Ciardi +4
High-resolution ground-based optical speckle and near-infrared adaptive optics images are taken to search for stars in close angular proximity to host stars of candidate planets id…
Kepler-432: a red giant interacting with one of its two long period giant planets
Samuel N. Quinn, Timothy R. White, David W. Latham +28
We report the discovery of Kepler-432b, a giant planet () transiting an evolved star $(M_\star =…
Most Sub-Arcsecond Companions of Kepler Exoplanet Candidate Host Stars are Gravitationally Bound
Elliott P. Horch, Steve B. Howell, Mark E. Everett +1
Using the known detection limits for high-resolution imaging observations and the statistical properties of true binary and line-of-sight companions, we estimate the binary fractio…
Followup Observations of SDSS and CRTS Candidate Cataclysmic Variables
Paula Szkody, Mark E. Everett, Steve B. Howell +4
We present photometry of 11 and spectroscopy of 35 potential cataclysmic variables from the Sloan Digital Sky Survey, the Catalina Real-Time Transient Survey and vsnet-alerts. The…
An Earth-sized Planet in the Habitable Zone of a Cool Star
Elisa V. Quintana, Thomas Barclay, Sean N. Raymond +20
The quest for Earth-like planets represents a major focus of current exoplanet research. While planets that are Earth-sized and smaller have been detected, these planets reside in…
Limits on Stellar Companions to Exoplanet Host Stars With Eccentric Planets
Stephen R. Kane, Steve B. Howell, Elliott P. Horch +6
Though there are now many hundreds of confirmed exoplanets known, the binarity of exoplanet host stars is not well understood. This is particularly true of host stars which harbor…
