FIN 47 chi 1 Hya.
Masses and bolometric magnitudes are derived for the two components of Msn1999a
this system by Mason et al. (1999), based on assumed spectral types
and available parallaxes.
Hipparcos astrometric solution adopted some elements from the orbit of HIP1997d
van den Bos (1957). B__1957a
A new orbital analysis of this system is in progress, some three
decades after van den Bos published his solution. Hrt1996b
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 3.79 +/- 0.19, 2.70, and 1.41 Msun, respectively. Mlk2012
