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…
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…
