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…
Confirmation of the Planet Hypothesis for the Long-period Radial Velocity Variations of Beta Geminorum
A. P. Hatzes, W. D. Cochran, M. Endl E. W. Guenther +6
We present precise stellar radial velocity measurements for the K giant star Beta Gem spanning over 25 years. These data show that the long period low amplitude radial velocity var…
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…
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…
