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.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Combined solution from astrometry, spectroscopy, and parallax.
Solution yields mass and orbital parallax determination. Sgr2000
Martin et al. (1998) derive component masses 0.327 +/- 0.045 and
0.558 +/- 0.047 Msun. Mig1998
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. Jnn2012
LDS 573 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. Jnn2014
