Notes for HR 810
alias iota Hor, HD 17051by Jean Schneider
update: 11 September 2001
The planet(s):
- Detection method: Radial Velocity at ESO-CAT
- Basic data:
Name: HR 810 b M.sini: 2.25 ± 0.18 MJ Semi-major axis: 0.925 ± 0.104 AU Orbital period: 320.1 ± 2.1 d. Eccentricity: 0.161 ± 0.069 Omega (deg): 316 T_peri (JD-2450000): -388.00 Inclinaison: - - Remarks:
11 Sep. 01: ESO retraction: no more dust disk around iota Hor (Aug. 01)
22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 24 MJ and inclination of 5.5o
The systems has a dust disc (Adonis Team at ESO):
- radius 65 AU
- inclination 42њ - References:
