A ~7.5 M⊕ Planet Orbiting the Nearby Star, GJ 876*
High-precision, high-cadence radial velocity monitoring over the past 8 yr at the W. M. Keck Observatory reveals evidence for a third planet orbiting the nearby (4.69 pc) dM4 star GJ 876. TheExpand
A Pair of Resonant Planets Orbiting GJ 876
Precise Doppler measurements during 6 yr from the Lick and Keck observatories reveal two planets orbiting GJ 876 (M4V). The orbital Ðt yields companion masses of M sin i \ 0.56 and 1.89 orbital M J ,Expand
THE LICK-CARNEGIE EXOPLANET SURVEY: A URANUS-MASS FOURTH PLANET FOR GJ 876 IN AN EXTRASOLAR LAPLACE CONFIGURATION*
Continued radial velocity (RV) monitoring of the nearby M4V red dwarf star GJ 876 with Keck/High Resolution Echelle Spectrograph has revealed the presence of a Uranus-mass fourth planetary companionExpand
The LCES HIRES/Keck Precision Radial Velocity Exoplanet Survey
This document is the Accepted Manuscript version of the following article: R. Paul Butler, et al, The LCES HIRES/Keck Precision Radial Velocity Exoplanet Survey, The Astronomical Journal, Vol 153Expand
Systemic: A Testbed for Characterizing the Detection of Extrasolar Planets. I. The Systemic Console Package
We present the Systemic Console, a new all-in-one, general-purpose software package for the analysis and combined multiparameter fitting of Doppler radial velocity (RV) and transit timingExpand
Rapid heating of the atmosphere of an extrasolar planet
TLDR
8-μm photometric observations of the planet HD 80606b during a 30-hour interval bracketing the periastron passage of its extremely eccentric 111.4-day orbit indicate the global heating rate is ∼4.5 h, in comparison with 3–5 days in Earth’s stratosphere, and a secondary eclipse for the planet is detected.

A SUPER-EARTH AND TWO NEPTUNES ORBITING THE NEARBY SUN-LIKE STAR 61 VIRGINIS
We present precision radial velocity data that reveal a multiple exoplanet system orbiting the bright nearby G5V star 61 Virginis. Our 4.6 years of combined Keck/HIRES and Anglo-Australian TelescopeExpand
A planetary system around the nearby M dwarf GJ 667C with at least one super-earth in its habitable zone
We re-analyze 4 years of HARPS spectra of the nearby M1.5 dwarf GJ 667C available through the European Southern Observatory public archive. The new radial velocity (RV) measurements were obtainedExpand
The Lick-Carnegie Exoplanet Survey: A 3.1 M ⊕ Planet in the Habitable Zone of the Nearby M3V Star Gliese 581
We present 11 years of HIRES precision radial velocities (RVs) of the nearby M3V star Gliese 581, combining our data set of 122 precision RVs with an existing published 4.3-year set of 119 HARPSExpand
Formation and Detectability of Terrestrial Planets around α Centauri B
We simulate the formation of planetary systems around α Centauri B. The N-body accretionary evolution of a Σ ∝ r−1 disk populated with 400-900 lunar-mass protoplanets is followed for 200 Myr. AllExpand
