A long-period planet orbiting a nearby Sun-like star
Hugh R. A. Jones, R. Paul Butler, C. G. Tinney +10
The Doppler wobble induced by the extra-solar planet HD 134987b was first detected by data from the Keck Telescope nearly a decade ago, and was subsequently confirmed by data from…
A Super-Earth and two Neptunes Orbiting the Nearby Sun-like star 61 Virginis
Steven S. Vogt, Robert A. Wittenmyer, R. Paul Butler +10
We present precision radial velocity (RV) data that reveal a multiple exoplanet system orbiting the bright nearby G5V star 61 Virginis. Our 4.6 years of combined Keck/HIRES and Ang…
The Frequency of Low-mass Exoplanets
S. J. O'Toole, H. R. A. Jones, C. G. Tinney +5
We report first results from the Anglo-Australian Telescope Rocky Planet Search - an intensive, high-precision Doppler planet search targeting low-mass exoplanets in contiguous 48…
A Search for Multi-Planet Systems Using the Hobby-Eberly Telescope
Robert A. Wittenmyer, Michael Endl, William D. Cochran +2
Extrasolar multiple-planet systems provide valuable opportunities for testing theories of planet formation and evolution. The architectures of the known multiple-planet systems dem…
