Hinzel, David H.
|
Pair A elements in the table. Pair B elements = HJD 2453857.4361 + 1.4200401 x E. Slow apsidal motion with periods of 116 and 111 years for pair A and pair B respectively. Orbital period of the two eclipsing binaries around a common barycenter is 2.91 years. Additional component 1" away makes this a quintuple system. System has nearly coplanar orbits. |

|
Quadruple system of two pairs of eclipsing binaries. The second system consists of a A2V+A4V binary with P=1.420033d. |
