We present a summary of the McDonald Observatory Planetary Search program. We first summarize results on the star ∊ Eridani, in which we combine McDonald Observatory data with data from CFHT, Lick, and ESO, to detect a planet in orbit around this very nearby star. We then concentrate on results from the first 4 years of the Texas Hyades survey using the HIRES spectrograph on Keck 1. The Hyades constitute a very homogeneous sample of stars, in which the major independent variable is the stellar mass. In this survey, we have achieved 3 m s−1 internal error on a sample of about 100 Hyades dwarfs. We discuss the rms radial velocity jitter of the sample stars, and its relationship to spectral type, stellar rotation, and chromospheric activity.
