Characterizing the Cool KOIs IV: Kepler-32 as a prototype for the formation of compact planetary systems throughout the Galaxy
Jonathan J. Swift, John Asher Johnson, Timothy D. Morton +4
The Kepler space telescope has opened new vistas in exoplanet discovery space by revealing populations of Earth-sized planets that provide a new context for understanding planet fo…
Robo-AO: An Autonomous Laser Adaptive Optics and Science System
Christoph Baranec, Reed Riddle, A. N. Ramaprakash +15
Robo-AO, a fully autonomous, laser guide star adaptive optics and science system, is being commissioned at Palomar Observatory's 60-inch telescope. Here we discuss the instrument,…
Model-Independent Stellar and Planetary Masses from Multi-Transiting Exoplanetary Systems
Benjamin T. Montet, John Asher Johnson
Precise exoplanet characterization requires precise classification of exoplanet host stars. The masses of host stars are commonly estimated by comparing their spectra to those pred…
A paucity of proto-hot Jupiters on super-eccentric orbits
Rebekah I. Dawson, Ruth A. Murray-Clay, John Asher Johnson
Gas giant planets orbiting within 0.1 AU of their host stars, unlikely to have formed in situ, are evidence for planetary migration. It is debated whether the typical hot Jupiter s…
The TRENDS High-Contrast Imaging Survey. I. Three Benchmark M-dwarfs Orbiting Solar-type Stars
Justin R. Crepp, John Asher Johnson, Andrew W. Howard +8
We present initial results from a new high-contrast imaging program dedicated to stars that exhibit long-term Doppler radial velocity accelerations (or "trends"). The goal of the T…
The TRENDS High-Contrast Imaging Survey. II. Direct Detection of the HD 8375 Tertiary
Justin R. Crepp, John Asher Johnson, Andrew W. Howard +6
We present the direct imaging detection of a faint tertiary companion to the single-lined spectroscopic binary HD 8375 AB. Initially noticed as an 53 m/s/yr Doppler acceleration by…
