The Dynamical Mass and Three-Dimensional Orbit of HR7672B: A Benchmark Brown Dwarf with High Eccentricity
Justin R. Crepp, John Asher Johnson, Debra A. Fischer +10
The companion to the G0V star HR7672 directly imaged by Liu et al. (2002) has moved measurably along its orbit since the discovery epoch, making it possible to determine its dynami…
Non-Detection of the Putative Substellar Companion to HD 149382
Jackson M. Norris, Jason T. Wright, Richard A. Wade +2
It has been argued that a substellar companion may significantly influence the evolution of the progenitors of sdB stars. Recently, the bright sdB star HD 149382 has been claimed t…
A High Eccentricity Component in the Double Planet System Around HD 163607 and a Planet Around HD 164509
Matthew J. Giguere, Debra A. Fischer, Andrew W. Howard +7
We report the detection of three new exoplanets from Keck Observatory. HD 163607 is a metal-rich G5IV star with two planets. The inner planet has an observed orbital period of 75.2…
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…
TERMS Photometry of Known Transiting Exoplanets
Diana Dragomir, Stephen R. Kane, Genady Pilyavsky +10
The Transit Ephemeris Refinement and Monitoring Survey (TERMS) conducts radial velocity and photometric monitoring of known exoplanets in order to refine planetary orbits and predi…
Retired A Stars and Their Companions: Eighteen New Jovian Planets
John Asher Johnson, Christian Clanton, Andrew W. Howard +9
We report the detection of eighteen Jovian planets discovered as part of our Doppler survey of subgiant stars at Keck Observatory, with follow-up Doppler and photometric observatio…
