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…
A Gyrochronology and Microvariability Survey of the Milky Way's Older Stars Using Kepler's Two-Wheels Program
Saurav Dhital, Terry D. Oswalt, Philip S. Muirhead +7
Even with the diminished precision possible with only two reaction wheels, the Kepler spacecraft can obtain mmag level, time-resolved photometry of tens of thousands of sources. Th…
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…
Characterizing the Cool KOIs. V. KOI-256: A Mutually Eclipsing Post-Common Envelope Binary
Philip S. Muirhead, Andrew Vanderburg, Avi Shporer +23
We report that Kepler Object of Interest 256 (KOI-256) is a mutually eclipsing post-common envelope binary (ePCEB), consisting of a cool white dwarf (M = 0.592 +/- 0.089 MSun, R =…
Optimizing Doppler Surveys for Planet Yield
Michael Bottom, Philip S. Muirhead, John Asher Johnson +1
One of the most promising methods of discovering nearby, low-mass planets in the habitable zones of stars is the precision radial velocity technique. However, there are many challe…
