We report that HD 110067, the recently announced host star of a resonant sextuplet of transiting sub-Neptunes, is not a single star as claimed in the discovery paper, but a wide hi…
Characterizing the Cool KOIs II. The M Dwarf KOI-254 and its Hot Jupiter
John Asher Johnson, J. Zachary Gazak, Kevin Apps +12
We report the confirmation and characterization of a transiting gas giant planet orbiting the M dwarf KOI-254 every 2.455239 days, which was originally discovered by the Kepler mis…
M2K: II. A Triple-Planet System Orbiting HIP 57274
Debra A. Fischer, Eric Gaidos, Andrew Howard +14
Doppler observations from Keck Observatory have revealed a triple planet system orbiting the nearby mid-type K dwarf, HIP 57274. The inner planet, HIP 57274b, is a super-Earth with…
LHS6343C: A Transiting Field Brown Dwarf Discovered by the Kepler Mission
John Asher Johnson, Kevin Apps, J. Zachary Gazak +7
We report the discovery of a brown dwarf that transits one member of the M+M binary system LHS6343AB every 12.71 days. The transits were discovered using photometric data from the…
The California Planet Survey I. Four New Giant Exoplanets
Andrew W. Howard, John Asher Johnson, Geoffrey W. Marcy +12
We present precise Doppler measurements of four stars obtained during the past decade at Keck Observatory by the California Planet Survey (CPS). These stars, namely, HD 34445, HD 1…
M2K: I. A Jovian mass planet around the M3V star HIP79431
Kevin Apps, Kelsey I. Clubb, Debra A. Fischer +10
Doppler observations from Keck Observatory reveal the presence of a planet with Msini of 2.1 Mjup orbiting the M3V star HIP79431. This is the sixth giant planet to be detected in D…
