Friends of Hot Jupiters I: A Radial Velocity Search for Massive, Long-Period Companions to Close-In Gas Giant Planets
Heather A. Knutson, Benjamin J. Fulton, Benjamin T. Montet +10
In this paper we search for distant massive companions to known transiting gas giant planets that may have influenced the dynamical evolution of these systems. We present new radia…
Electric Field Conjugation with the Project 1640 coronagraph
Eric Cady, Christoph Baranec, Charles Beichman +25
The Project 1640 instrument on the 200-inch Hale telescope at Palomar Observatory is a coronagraphic instrument with an integral field spectrograph at the back end, designed to fin…
The Kappa Andromedae System: New Constraints on the Companion Mass, System Age & Further Multiplicity
Sasha Hinkley, Laurent Pueyo, Jacqueline K. Faherty +29
Kappa Andromedae is a B9IVn star at 52 pc for which a faint substellar companion separated by 55 AU was recently announced. In this work, we present the first spectrum of the compa…
The nearby, young, isolated, dusty star HD 166191
Adam Schneider, Inseok Song, Carl Melis +4
We report an in-depth study of the F8-type star HD 166191, identified in an ongoing survey for stars exhibiting infrared emission above their expected photospheres in the Wide-fiel…
KELT-6b: A P~7.9 d Hot Saturn Transiting a Metal-Poor Star with a Long-Period Companion
Karen A. Collins, Jason D. Eastman, Thomas G. Beatty +39
We report the discovery of KELT-6b, a mildly-inflated Saturn-mass planet transiting a metal-poor host. The initial transit signal was identified in KELT-North survey data, and the…
WASP-12b and HAT-P-8b are Members of Triple Star Systems
Eric B. Bechter, Justin R. Crepp, Henry Ngo +9
We present high spatial resolution images that demonstrate the hot Jupiters WASP-12b and HAT-P-8b orbit the primary star of hierarchical triple star systems. In each case, two dist…
