Detection of Planetary and Stellar Companions to Neighboring Stars via a Combination of Radial Velocity and Direct Imaging Techniques
Stephen R. Kane, Paul A. Dalba, Zhexing Li +13
The sensitivity of radial velocity (RV) surveys for exoplanet detection are extending to increasingly long orbital periods, where companions with periods of several years are now b…
Discovery of a White Dwarf Companion to HD 159062
Lea A. Hirsch, David R. Ciardi, Andrew W. Howard +11
We report on the discovery of a white dwarf companion to the nearby late G dwarf star, HD 159062. The companion is detected in 14 years of precise radial velocity (RV) data, and in…
Mass Constraints of the WASP-47 Planetary System from Radial Velocities
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +19
We report precise radial velocity (RV) measurements of WASP-47, a G star that hosts three transiting planets in close proximity (a hot Jupiter, a super-Earth and a Neptune-sized pl…
The Kepler Follow-Up Observation Program. I. A Catalog of Companions to Kepler Stars from High-Resolution Imaging
E. Furlan, D. R. Ciardi, M. E. Everett +16
We present results from high-resolution, optical to near-IR imaging of host stars of Kepler Objects of Interest (KOIs), identified in the original Kepler field. Part of the data we…
Speckle Imaging Excludes Low-Mass Companions Orbiting the Exoplanet Host Star TRAPPIST-1
Steve B. Howell, Mark E. Everett, Elliott P. Horch +4
We have obtained the highest resolution images available of TRAPPIST-1 using the Gemini-South telescope and our speckle imaging camera. Observing at 692 and 883 nm, we reached the…
Stellar Companions to the Exoplanet Host Stars HD 2638 and HD 164509
Justin M. Wittrock, Stephen R. Kane, Elliott P. Horch +5
An important aspect of searching for exoplanets is understanding the binarity of the host stars. It is particularly important because nearly half of the solar-like stars within our…
