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…
Exploring The Frequency Of Close-In Jovian Planets Around M Dwarfs
Michael Endl, William D. Cochran, Martin Kuerster +4
We discuss our high precision radial velocity results of a sample of 90 M dwarfs observed with the Hobby-Eberly Telescope and the Harlan J. Smith 2.7 m Telescope at McDonald Observ…
The First Extrasolar Planet Discovered with a New Generation High Throughput Doppler Instrument
Jian Ge, Julian van Eyken, Suvrath Mahadevan +17
We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a you…
Detection Limits from the McDonald Observatory Planet Search Program
Robert A. Wittenmyer, Michael Endl, William D. Cochran +4
Based on the long-term radial-velocity surveys carried out with the McDonald Observatory 2.7m Harlan J. Smith Telescope from 1988 to the present, we derive upper limits to long-per…
Determination Of The Orbit Of The Planetary Companion To The Metal Rich Star HD 45350
Michael Endl, William D. Cochran, Robert A. Wittenmyer +1
We present the precise radial velocity (RV) data for the metal-rich star HD 45350 collected with the Harlan J. Smith (HJS) 2.7 m telescope and the Hobby-Eberly Telescope (HET) at M…
