A Six-Planet System Around the Star HD 34445
Steven S. Vogt, R. Paul Butler, Jennifer Burt +10
We present a new precision radial velocity dataset that reveals a multi-planet system orbiting the G0V star HD 34445. Our 18-year span consists of 333 precision radial velocity obs…
Astrometric Constraints on the Masses of Long-Period Gas Giant Planets in the TRAPPIST-1 Planetary System
Alan P. Boss, Alycia J. Weinberger, Sandra A. Keiser +3
Transit photometry of the M8V dwarf star TRAPPIST-1 (2MASS J23062928-0502285) has revealed the presence of at least seven planets with masses and radii similar to that of Earth orb…
The LCES HIRES/Keck Precision Radial Velocity Exoplanet Survey
R. Paul Butler, Steven S. Vogt, Gregory Laughlin +8
We describe a 20-year survey carried out by the Lick-Carnegie Exoplanet Survey Team (LCES), using precision radial velocities from HIRES on the Keck-I telescope to find and charact…
