discov_num notes refcode
STF1669 58 Crv. Both A and B are spectroscopic binaries (A is SB1), with
periods of 44.4 and 1.46d. Both may also be variable.
Period of AB estimated at 4500y, AC at 150,000y. Tok2006
AB: H N 38. MEv2010
The B component of STF1669 is the spectroscopic eclipsing binary VV
Crv. Fekel et al. (2013) derive an orbit based on light and velocity
curves with P=3.1445d and e=0.0852. Both components are F5 dwarfs; V
magnitudes are 6.099 and 7.536, and masses are 1.978 +/- 0.010 and
1.513 +/- 0.008 Msun. Fek2013b
