B 2351 iot 1 Lib = 24 Lib. Alternate spectrum of Aa: ApSi.
Double-lined spectrum, frequently blended. The second spectrum may
belong, not to the visual companion, but to a third star, since the
RV variation - if real - is faster and larger than the visual orbit
with its low inclination could cause.
This system has crude Delta m estimates from lunar occultation of
about 1.3 magnitudes in both red and blue. Bvr1979b
Masses and bolometric magnitudes are derived for the two components
of this system, based on assumed spectral types and available
parallaxes. Msn1999a
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Aa,Ab: Orbits of this system have been published by Heintz (1982) Hei1982c
and later by Mason (1994, 1995); further analysis is in Msn1994
progress. Msn1995b
Aa,Ab: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 6.20 +/- 0.56, 5.14, and 2.82 Msun, respectively. Mlk2012
H 6 44 AB: H VI 44.
