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. |

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. |
