Abstract

Photoelectric uvby, H-beta photometry is presented for the early B-type eclipsing binary OX Cassiopeiae. A new ephemeris is determined. Photometric elements are derived using the WINK model and combined with recent spectroscopic observations to determine the following absolute parameters: for the primary star A-mass = 7.2 + or - 0.5 solar masses, R(A) = 4.69 + or - 0.3 solar radii, and T(e,A) = 24,000 K; and for the secondary star B-mass = 6.3 + or - 0.5 solar masses, R(B) = 4.22 + or - 0.3 solar radii, and T(e,B) = 23,400 K. The spectral types of both components are estimated photometrically to be B2 V. The system is found to be detached. Rapid apsidal motion of the system is confirmed, and the possible presence of a third source of light is explored. The distance and (B-V) color excess are determined for the system to be 2.1 + or - 0.2 kpc and 0.50 + or - 0.06, respectively, which preclude OX Cas from being a member of the nearby open cluster NGC 381.
