DUN 38 A is a spectroscopic binary. B is CD-43@2907. AC = LDS 175.
HIP 34065. See Allen et al. (2000) for information on metallicity, AlC2000
age, galactic orbital parameters, etc.
AC: SHY 36. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
TOK 390 Ca,Cb: HIP 34052 = HD 53680 = HIP 34065C = GJ 264 is a spectroscopic
and astrometric binary for which Sahlmann et al. (2011) give an orbit SaJ2011
with P=1688d = 4.62yr and an estimated semi-major axis of 0".15. There
is also an astrometric orbit (Makarov et al. 2008) with P=4.11yr that Mkr2008
predicts theta = 327deg for the moment of our first observation. The
binary is resolved at 0".23, dI = 4.4mag and shows some orbital
motion. The binary makes a quadruple system together with components A
and B (GJ 264.1 and 264) that form a 20".5 pair at 185" from C. The B
component was also observed here and found unresolved. Tok2015c
Ca,Cb: Sahlmann (2011): orb. C: P=1688.6d e=0.475 K1=1.24 SaJ2011
