Notes for rho CrB

HD 143761, HR 5968

update: 4 November 2001

The planet(s):

Detection method: Radial Velocity

Basic data:

Name:	rho CrB
M.sini:	1.1 M_J
Semi-major axis:	0.23 AU
Orbital period:	39.645 d.
Eccentricity:	0.028 ± 0.15
Omega (deg):	299
T_peri (JD-2450000):	84.66
Inclinaison:	-

Remarks: 22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 115 M_J and inclination of 0.5^o
Circumstellar disk found at 1.6, 2,1 2.3 and 2.5 microns by Trilling et al (1999). From the disk inclination (46 degrees ⁺⁴_-7 degrees) a planet mass of 1.5 M_J can be infered. Comment by G. Marcy & P. Butler.
