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⊕.
