The metallicity distribution and hot Jupiter rate of the Kepler field: Hectochelle High-resolution spectroscopy for 776 Kepler target stars
Xueying Guo, John A. Johnson, Andrew W. Mann +3
The occurrence rate of hot Jupiters from the Kepler transit survey is roughly half that of radial velocity surveys targeting solar neighborhood stars. One hypothesis to explain thi…
The Pan-Pacific Planet Search VI: Giant planets orbiting HD 86950 and HD 222076
Robert A. Wittenmyer, M. I. Jones, Jinglin Zhao +5
We report the detection of two new planets orbiting the K giants HD 86950 and HD 222076, based on precise radial velocities obtained with three instruments: AAT/UCLES, FEROS, and C…
The Habitability of Planets Orbiting M-dwarf Stars
Aomawa L. Shields, Sarah Ballard, John Asher Johnson
The prospects for the habitability of M-dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low-mass sta…
Evidence for the Direct Detection of the Thermal Spectrum of the Non-Transiting Hot Gas Giant HD 88133 b
Danielle Piskorz, Bjorn Benneke, Nathan R. Crockett +10
We target the thermal emission spectrum of the non-transiting gas giant HD 88133 b with high-resolution near-infrared spectroscopy, by treating the planet and its host star as a sp…
Kepler-21b: A rocky planet around a V = 8.25 magnitude star
Mercedes Lopez-Morales, Raphaelle D. Haywood, Jeffrey L. Coughlin +36
HD 179070, aka Kepler-21, is a V = 8.25 F6IV star and the brightest exoplanet host discovered by Kepler. An early detailed analysis by Howell et al. (2012) of the first thirteen mo…
The Orbit and Mass of the Third Planet in the Kepler-56 System
Oderah Justin Otor, Benjamin T. Montet, John Asher Johnson +20
While the vast majority of multiple-planet systems have their orbital angular momentum axes aligned with the spin axis of their host star, Kepler-56 is an exception: its two transi…
