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…
HD 91669b: A New Brown Dwarf Candidate from the McDonald Observatory Planet Search
Robert A. Wittenmyer, Michael Endl, William D. Cochran +4
We report the detection of a candidate brown dwarf orbiting the metal-rich K dwarf HD 91669, based on radial-velocity data from the McDonald Observatory Planet Search. HD 91669b is…
The Extrasolar Planet epsilon Eridani b - Orbit and Mass
G. Fritz Benedict, Barbara E. McArthur, George Gatewood +11
Hubble Space Telescope observations of the nearby (3.22 pc), K2 V star epsilon Eridani have been combined with ground-based astrometric and radial velocity data to determine the ma…
Long-Period Objects in the Extrasolar Planetary Systems 47 UMa and 14 Her
Robert A. Wittenmyer, Michael Endl, William D. Cochran
The possible existence of additional long-period planetary-mass objects in the extrasolar planetary systems 47 UMa and 14 Her is investigated. We combine all available radial-veloc…
