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. |

AB: Optical pair, based on study of relative motion of the components |
|
|
using the method of apparent motion parameters. |

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. |

|
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. |
