The planet(s):
- Detection method: Radial Velocity
- Basic data:
The star:
Name: Gl 876 b Gl 876 c M.sini: 1.89 MJ 0.56 MJ Semi-major axis: 0.21 AU 0.13 AU Orbital period: 61.02 d. 30.1 d Eccentricity: 0.10 0.27 Inclination sini = 0.6 ? sini = 0.6 ? Omega (deg): 333 330 T_peri (JD-2450000): 106.2 31.4 Inclinaison: - - Remarks:- 7 march 01: From stability considerations, Lauglin & Chambers argue that "the facteors for the 2 planets are likely in the 1.25 - 2.0 range" (implying a sini of ~ 0.6 (Chambers & Laughlin, 2001)
- Circumstellar disk searched for at UKIRT and KECK but not found (Trilling et al. 1999, 2000)
