Abstract
We report several new reliable times of minimum of the eccentric eclip sing binary OX Cas (P = 2.48934 days E = 0.04, V = 9.92 mag, B2V + B2V ). The O-C diagram is analyzed found in the literature and improved va lues 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 +/- 0.7 yr and the internal structure constant (k) over bar( 2,obs) = 0.0060.
