ADC_Keywords: Planets ; Radial velocities Keywords: stars: individual: GJ876 - planetary systems - techniques: radial velocities - methods: observational - methods: numerical - celestial mechanics Abstract: Precise radial-velocity measurements for data acquired with the HARPS spectrograph infer that three planets orbit the M4 dwarf star GJ 876. In particular, we confirm the existence of planet d, which orbits every 1.93785-days. We find that its orbit may have significant eccentricity (e=0.14), and deduce a more accurate estimate of its minimum mass of 6.3M.
