discov_num notes refcode
HDS3158 Cvetkovic et al. (2014) derive spectral types G4 and K3, masses 1.07
and 0.79 Msun. Dynamical parallax is 17.56 +/- 0.44 mas. Cve2014
A 111.1d spectroscopic solution for the B component has been found Tok2018d
making this a triple system.
Synthetic Spectrum gives Bt mags of 12.19 & 14.02 for Ba,Bb and 11.12 Mda2019
and 12.67 for Vt. The solution for the three components A, Ba and Bb
Teff = 5836 +/- 80, 5115 +/- 80, and 4500 +/- 80, degrees Kelvin,
R = 1.09 +/- 0.039, 0.596 +/- 0.05, and 0.49 +/- 0.06, \rsun,
