KUI 75 |
Wolf 630. |
|
|
A flare star, V1054 Oph. One of the shortest orbital period, for pairs |
|
|
resolved first by naked eye. The radial velocities indicate a third |
|
|
component. The intrinsically very faint star VB 8 (mag 17, 220") is |
|
|
also a member of the system. There is strong evidence that it is an |
|
|
astrometric binary. The pair is the large proper-motion star Wolf 630 |
|
|
which forms a multiple system with the SB Wolf 629 (mag.11.7, 72", |
|
|
sdM4) and VBS 8 (mag. about 18, 221"), so the whole system is probably |
|
|
a septuple. There is strong evidence that VBS 8 is an astrometric |
|
|
binary. Eggen suggests that the group is part of a large moving |
Egg1965b |
|
cluster. He has observed an UV flare on Wolf 630. According to |
|
|
Soderhjelm, the mass ratio and mass sum require the secondary to be a |
Sod1999 |
|
closer SB. Unuseable HIP solution. |

Combined solution from astrometry, spectroscopy, and parallax. |

Solution yields mass and orbital parallax determination. |

Martin et al. (1998) derive component masses 0.327 +/- 0.045 and |

0.558 +/- 0.047 Msun. |

KUI 75AB is also known as Gliese 644 (B is an SB1 star), component C |
|
|
is Gliese 643, also an SB1 star. Component F is VB 8 and is also known |
|
|
as Gliese 644C. |
Och2010 |
|
Also known as GJ 644, this is a well-known and much studied triple |
|
|
system (e.g. Segransan et al. 2000), of which we resolve the wider AB |
Sgr2000 |
|
pair (the secondary is a spectroscopic binary with a 3 day period). In |
|
|
addition, there are two much wider components known to share a common |
|
|
proper motion with GJ 644, making the system a likely quintuple. Since |
|
|
there are so many existing astrometric points of the AB pair in the |
|
|
literature, we do not give an extensive list in Table 4, but rather |
|
|
refer the reader to Segransan et al., where there is a full orbital |
|
|
analysis of the close triple system. |

AC: While VB 8 itself is single in the AstraLux sensitivity range, it |
|
|
is part of a higher-order multiple (at least triple, possibly |
|
|
quintuple) as a known 1500 au companion (C component) to GJ 644, which |
Jnn2012 |
|
was discussed in our Janson et al. (2012) study. |
