HDS1850 | Aa,Ab: Hipparcos parallax 23.72 +/- 0.60 mas. Dynamical parallax 23.6 | |
mas, masses 1.56 and 0.79 Msun. This is a chromospherically active G0V | ||
dwarf and a ROSAT X-ray source. There are at least four components in | ||
the system: Aa1,Aa2 is a double-lined spectroscopic and eclipsing | ||
binary with 4.2 d period, Aa,Ab is the pair considered here, and the | ||
visual companion B at 25.5" is physical. The orbits of Aa1,Aa2 and | ||
Aa,Ab may be co-planar. | Tok2012b | |
Aa,Ab: GJ 2099. Aa is SB2E, P=4.233d | Tok2014d |
