A 1777 65 UMa. The primary is the eclipsing binary DN UMa,
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Discrepant 1995.3159 speckle measure found not due to a typographical Hrt1997
error in theta, following reexamination of original data by authors.
Presumably there was an identification error while pointing telescope,
although no probable match to known close pairs in the vicinity has
been found.
65 UMa After subtracting out the effects of the 118y AB pair, Zasche et al.
(2012) find a 640d variation, which they attribute to a closer Aa,Ab
pair. The 1.7d eclipsing pair DN UMa, then, is assumed to be Aa1,Aa2.
Their analysis determines a distance 234 +/- 29 pc to the system
(compared with 212 +/- 30 pc from the revised Hipparcos reduction of
van Leeuwen 2007), a and total mass of 8.25 +/- 1.85 Msun. Derived vlF2007
spectral types, masses, and radii of the components are as follows:
Aa1 A7 1.74 +/- 0.06 Msun 1.86 +/- 0.08 Rsun
Aa2 A7 1.71 0.06 1.81 0.08
Ab A1 2.4 0.4
B 2.4 2.0 Zas2012b
STF1579 STTA113 = STFA 20.
AB,C: H 1 72. MEv2010
May be a physical septuple: the 1.7d eclipsing pair (2), the 640d
spectroscopic component (+1), the 118y resolved pair A 1777 (+1)
and the wider cpm pair (+1) STF1579AB,D. STF1579AB,C also has similar
proper motion and may be physical and the D component has been split
interferometrically (BAG 46Da,Db).
