Abstract (from CDS):

Precise radial velocity observations of the nearby M4 dwarf Gl876 with the Observatoire de Haute Provence 1.93m telescope and the new 1.20m swiss telescope at la Silla indicate the presence of a jovian mass companion to this star. The orbital fit to the data gives a period of 60.8 days, a velocity amplitude of 246m/s and an eccentricity of 0.34. Assuming that Gl876 has a mass of 0.3M, the mass function implies a mass for the companion of 2/sin i Jupiter masses.
