Photometric elements, absolute dimensions and evolutionary status of the eclipsing binary HU Tauri

Abstract

The photometric elements of HU Tauri are derived from an analysis of its B and V light curve using the Wilson and Devinney (1971) light curve synthesis method. The photometric elements suggest that HU Tauri is a semi-detached system and the primary minimum in its light curve is due to an occultation. Combining the photometric elements and spectroscopic orbital elements the absolute dimensions of the system are derived. The cool and less massive secondary has over filled its Roche-lobe and it is over luminous for its mass. HU Tau is found to be a semi-detached system similar to Algol and delta Lib
