Rubidium and lead abundances in giant stars of the globular clusters M4 and M5
David Yong, David L. Lambert, Diane B. Paulson +1
We present measurements of the neutron-capture elements Rb and Pb for bright giants in the globular clusters M4 and M5. The clusters are of similar metallicity ([Fe/H] = -1.2) but…
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…
The Distances to Open Clusters from Main-Sequence Fitting. III. Improved Accuracy with Empirically Calibrated Isochrones
Deokkeun An, Donald M. Terndrup, Marc H. Pinsonneault +3
We continue our series of papers on open cluster distances with a critical assessment of the accuracy of main-sequence fitting using isochrones that employ empirical corrections to…
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…
Differential Radial Velocities and Stellar Parameters of Nearby Young Stars
Diane Paulson, Sylvana Yelda
Radial velocity searches for substellar mass companions have focused primarily on stars older than 1 Gyr. Increased levels of stellar activity in young stars hinders the detection…
