Apsidal motion in the eclipsing binary OX Cassiopeiae.

WOLF M., SAROUNOVA L. and DIETHELM R.

Abstract (from CDS):

We report several new reliable times of minimum of the eccentric eclipsing binary OX Cas (P=2.48934days, e=0.04, V=9.92mag, B2V+B2V). The O-C diagram is analyzed using all precise timings found in the literature and improved values for the elements of the apsidal motion and the internal structure constant are computed. We have found a short period of apsidal motion U=37.3±0.7yr and the internal structure constant k_2,obs=0.0060.
