STF 262 iot Cas. The primary is an unresolved binary, also an Alpha CVn
CHR 6 type variable, P = 1.74 d, and an astrometric, spectroscopic, and
spectrum variable (Rakos 1962; Klock, AJ 70, 176, 1965). The RV Rak1962
variation has not been confirmed.
Heintz (1962) also detected this pair as a submotion to the visual Hei1962
orbit of the AB pair with a period of 52 years and an amplitude of
0".11. Star C (mag. 8.4, dG4) is probably physical, but Hopmann Hop1960b
(1960) computed a hyperbolic orbit for it, as there is some RV
difference between C and A. q = periastron distance in the true
orbit = 6".7056. All hyperbolic orbits were rejected from the
Fourth and subsequent orbit catalogs. Wor1983
Soderhjelm gives Aa,Ab,B,C quadruple solution (AB in HIP). High Sod1999
mass-sum, strangely well-behaved speckle obs at Delta m=4?
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
Drummond et al. (2003) give solution for Aa,Ab incorporating motion of Dru2003
the AB pair. The authors conclude that the motion of B relative to
the CHR pair appears to be rectilinear. Masses of the CHR components
are derived.
1985.8540: This autocorrelogram was remeasured; the new results are
listed in the catalog. McA1987b
