HDO 245 |
del Cir. A variable and spectroscopic binary. |
|
|
Primary is eclipsing binary of Algol-type, period 3.90247d. |
Zas2014 |
|
This "field" object may belong to the "Pis 20" group of Mel'nik & |
|
|
Efremov (1995 SvAL 21, 10). The secondary classification is an |
|
|
estimate from Stickland et al. (1993). |
Stc1993 |
|
The Hipparcos Catalogue contains an eclipsing light curve. |
HIP1997a |
|
Classification of the B component of the optical pair is from Lindroos |
Lnd1985 |
|
(1985). Lindroos also finds a distance of 750 pc to this system. |

SNA 39 |
Aab,c: The primary is del Cir, an ellipsoidal variable star. Penny et |
|
|
al. (2001) performed a tomographic decomposition and found del Cir to |
Pny2001 |
|
be a triple system, with an eclipsing inner Aa,Ab pair (3.9d, a sin i |
|
|
= 11.44 Rsun) and a RV-stable Ac component. Mayer et al. (2014) |
MyP2014 |
|
established the hierarchical nature of the system, obtaining a 1644d |
|
|
period for the outer system. PIONIER clearly resolved the outer system |
|
|
as a 3.78mas pair. We did not detect the dV=7.8 B companion of Mason |
Msn1998a |
|
et al. (1998), but it may be just below our detection limit. |
