Notes for HD 38529

update: 1 October 2004

The planet(s):

• Detection method: Radial Velocity
• Basic data:

  Name:	HD 38529 b	HD 38529 c
  M.sini:	0.78 MJ	12.70 MJ
  Semi-major axis:	0.129 AU	3.68 AU
  Orbital period:	14.309 ± 0.05 d.	2174.3 ± 30.0 d.
  Eccentricity:	0.29 ± 0.02	0.36 ± 0.05
  Omega (deg):	87.7 ± 4.0	14.7 ± 10.0
  T_peri (JD-2450000):	5.8 ± 1.5	73.8 ± 35.0
  Inclination:	-	-

• Remarks:
  1. 22 Nov. 00: From astrometry Han et al (2000) claim a preliminary mass of 435 M_J and inclination of 0.1^o
  2. Exhibits coherent variations in residual velocities consistent with additional companion.
     24 Jul. 00: the source of RV variation remains speculative, depending on completion of one full orbit (Fischer et al 2000).
