[70.05] Precise Radial Velocity Measurements of 51 Pegasi with the AFOE Spectrograph

High-precision radial velocity measurements of the planetary candidate 51 Peg were obtained with the Advanced Fiber Optic Echelle (AFOE) spectrograph. With observations spanning more than two years, we confirm the 4-day variation first reported by Mayor and Queloz and examine the long-term velocity stability of this object. Explanations for the observed variations are discussed.
