discov_num notes refcode
FIN 381 Primary is 0.80d W UMa ecl. bin (V2388 Oph). Called a SB in the
Bright Star Catalogue; this may be motion in the visual pair.
Malkov et al. (2012) derive dynamical, photometric, and spectroscopic
masses of 4.83 +/- 1.03, 3.32, and 1.20 Msun, respectively. Mlk2012
Docobo & Andrade (2013) derive a dynamical parallax of 13.45 +/- 0.38
mas and component masses 1.76 +/- 0.22 and 1.38 +/- 0.18 Msun (based
on photometry of Yakut et al. 2004 A&A 417, 725) or 13.82 +/- 0.39
mas, 1.72 +/- 0.24 and 1.18 +/- 0.16 Msun (based on photometry of
Rucinski et al. 2002 AJ 124, 1738). See paper for extensive notes on
this system. Doc2013d
Zasche et al. (2014) derive a combined solution, including
interferometry plus times-of-minimia variations in the primary. They
determine a distance of 70.6 +/- 8.9pc and masses of 1.96 +/- 0.03 and
0.54 +/- 0.06 Msun. Zas2014b
