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…

Time-Varying Potassium in High-Resolution Spectra of the Type Ia Supernova 2014J

M. L. Graham, S. Valenti, B. J. Fulton +9

We present a time series of the highest resolution spectra yet published for the nearby Type Ia supernova (SN) 2014J in M82. They were obtained at 11 epochs over 33 days around pea…

Two planets around Kapteyn's star : a cold and a temperate super-Earth orbiting the nearest halo red-dwarf

Guillem Anglada-Escudé, Pamela Arriagada, Mikko Tuomi +21

Exoplanets of a few Earth masses can be now detected around nearby low-mass stars using Doppler spectroscopy. In this paper, we investigate the radial velocity variations of Kaptey…

The Lick-Carnegie Exoplanet Survey: Gliese 687b: A Neptune-Mass Planet Orbiting a Nearby Red Dwarf

Jennifer Burt, Steven S. Vogt, R. Paul Butler +5

Precision radial velocities from the Automated Planet Finder and Keck/HIRES reveal an M*sin(i) =18 +/- 2 Earth mass planet orbiting the nearby M3V star GJ 687. This planet has an o…

APF - The Lick Observatory Automated Planet Finder

Steven S. Vogt, Matthew Radovan, Robert Kibrick +45

The Automated Planet Finder (APF) is a facility purpose-built for the discovery and characterization of extrasolar planets through high-cadence Doppler velocimetry of the reflex ba…
