Characterizing the Cool KOIs. VII. Refined Physical Properties of the Transiting Brown Dwarf LHS 6343 C
Benjamin T. Montet, John Asher Johnson, Philip S. Muirhead +8
We present an updated analysis of LHS 6343, a triple system in the Kepler field which consists of a brown dwarf transiting one member of a widely-separated M+M binary system. By an…
Miniature Exoplanet Radial Velocity Array (MINERVA) I. Design, Commissioning, and First Science Results
Jonathan J. Swift, Michael Bottom, John A. Johnson +26
The MINiature Exoplanet Radial Velocity Array (MINERVA) is a US-based observational facility dedicated to the discovery and characterization of exoplanets around a nearby sample of…
Characterization of the atmosphere of the hot Jupiter HAT-P-32Ab and the M-dwarf companion HAT-P-32B
Ming Zhao, Joseph G. O'Rourke, Jason T. Wright +13
We report secondary eclipse photometry of the hot Jupiter HAT-P-32Ab, taken with Hale/WIRC in H and Ks bands and with Spitzer/IRAC at 3.6 and 4.5 micron. We carried out adaptive op…
The NASA-UC-UH Eta-Earth Program: IV. A Low-mass Planet Orbiting an M Dwarf 3.6 PC from Earth
Andrew W. Howard, Geoffrey W. Marcy, Debra A. Fischer +8
We report the discovery of a low-mass planet orbiting Gl 15 A based on radial velocities from the Eta-Earth Survey using HIRES at Keck Observatory. Gl 15 Ab is a planet with minimu…
Characterizing the Cool KOIs. VI. H- and K-band Spectra of Kepler M Dwarf Planet-Candidate Hosts
Philip S. Muirhead, Juliette Becker, Gregory A. Feiden +12
We present H- and K-band spectra for late-type Kepler Objects of Interest (the "Cool KOIs"): low-mass stars with transiting-planet candidates discovered by NASA's Kepler Mission th…
M-Dwarf Fast Rotators and the Detection of Relatively Young Multiple M-Star Systems
S. Rappaport, J. Swift, A. Levine +9
We have searched the Kepler light curves of ~3900 M-star targets for evidence of periodicities that indicate, by means of the effects of starspots, rapid stellar rotation. Several…
