Scientific paper

Currently every major telescope at McDonald Observatory is utilized in the search for extrasolar planets. We review the different planet search efforts and present the results of these programs. In particular we describe in detail the on-going precise Doppler surveys at the Harlan J. Smith 2.7 m telescope and at the Hobby-Eberly Telescope (HET). The highlight of the HET program was last year's discovery of a "Hot Neptune" in the ρ planetary system. With a mass of only 17 Earth masses this object demonstrates our ability to detect extrasolar planets with masses below the gas giant range.
