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 | |
