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…
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…
A 4-Planet System Orbiting the K0V Star HD 141399
Steven S. Vogt, R. Paul Butler, Eugenio J. Rivera +6
We present precision radial velocity (RV) data sets from Keck-HIRES and from Lick Observatory's new Automated Planet Finder Telescope and Levy Spectrometer on Mt. Hamilton that rev…
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…
Non-circular features in Saturn's D ring: D68
M. M. Hedman, J. A. Burt, J. A. Burns +1
D68 is a narrow ringlet located only 67,627 km (1.12 planetary radii) from Saturn's spin axis. Images of this ringlet obtained by the Cassini spacecraft reveal that this ringlet ex…
