discov_num notes refcode
WAL 32 After analysis of proper motions, radial velocities, etc. conclude
that A (= 51 Eri) and C (= GJ 330) comprise a wide physical binary and
are members of the young bet Pic moving group. Distance is ~30pc and
estimated orbital period is ~60,000y; pair form a very fragile system. Fgl2006
C component is GJ 3305; A and C are members of bet Pic moving group. Zuc2001b
BU 88 AB: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
KAS 1 Ca,Cb: Better known as GJ 3305, this binary is part of the beta Pic
moving group (Zuckerman et al. 2001), and is also bound to 51 Eri in a Zuc2001b
wide orbit (Feigelson et al. 2006) with a projected separation of 66". Fgl2006
The binarity of GJ 3305 was first reported by Kasper et al. (2007), Kas2007b
and has been observed with AstraLux on several occasions. Jnn2012
Ca,Cb: Montet et al (2015) derive a combined spectroscopic/astrometric
orbital solution, yielding masses 0.67 +/- 0.05 and 0.44 +/- 0.05
Msun, luminosities 0.112 +/- 0.007 and 0.043 +/- 0.005 Lsun, and an
age of 37 +/- 9 Gyr. Mtt2015
