STF1937 eta CrB = 2 CrB.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Masses and bolometric magnitudes are derived for the two components of
this system by Mason et al. (1999), based on assumed spectral types Msn1999a
Spectral types and masses of components assigned by ten Brummelaar et TtB2000
al., based on adaptive optics observations.
and available parallaxes.
Pourbaix gives combined solution for this resolved SB2, yielding Pbx2000b
orbital parallaxes and component masses.
Combined spectroscopic/astrometric solution of SB2. Calculated masses
1.243 +/- 0.054 and 1.100 +/- 0.039 Msun, distance 18.50 +/- 0.22 pc. Mut2010b
