Near-Infrared Spectroscopy of the Extrasolar Planet HR 8799 b
Brendan P. Bowler, Michael C. Liu, Trent J. Dupuy +1
[Abridged] We present 2.12-2.23 um high contrast integral field spectroscopy of the extrasolar planet HR 8799 b. Our observations were obtained with OSIRIS on the Keck II telescope…
Retired A Stars and Their Companions VI. A Pair of Interacting Exoplanet Pairs Around the Subgiants 24 Sextanis and HD200964
John Asher Johnson, Matthew Payne, Andrew W. Howard +10
We report radial velocity measurements of the G-type subgiants 24 Sextanis (=HD90043) and HD200964. Both are massive, evolved stars that exhibit periodic variations due to the pres…
Studying the Physical Diversity of Late-M Dwarfs with Dynamical Masses
Trent Dupuy, Michael Liu, Brendan Bowler +4
We present a systematic study of the physical properties of late-M dwarfs based on high-quality dynamical mass measurements and near-infrared (NIR) spectra. We use astrometry from…
A hot Jupiter orbiting the 1.7 Msun Subgiant HD102956
John Asher Johnson, Brendan P. Bowler, Andrew W. Howard +7
We report the detection of a giant planet in a 6.4950 day orbit around the 1.7 Msun subgiant HD102956. The planet has a semimajor axis a = 0.081 AU and minimum mass Msini = 0.96 Mj…
Retired A Stars and Their Companions IV. Seven Jovian Exoplanets from Keck Observatory
John Asher Johnson, Andrew W. Howard, Brendan P. Bowler +5
We report precise Doppler measurements of seven subgiants from Keck Observatory. All seven stars show variability in their radial velocities consistent with planet-mass companions…
