Photometric elements, absolute dimensions and evolutionary status of the eclipsing binary HU Tauri (HR 1471).

PARTHASARATHY M., SARMA M.B.K. and VIVEKANANDA RAO P.

Abstract (from CDS):

The photometric elements of HU Tauri are derived from an analysis of its blue and visual light curves using the Wilson & Devinney (1971ApJ...166..605W) light curve synthesis method. The photometric elements suggest that HU Tauri is a semidetached system and the primary minimum in its light curve is due to an occultation eclipse. Combining the photometric elements and spectroscopic orbital elements the absolute dimensions of the system are derived. The masses and radii of the B8 V primary and F8-G2 III-IV type secondary are found to be 4.68M☉, 2.9R☉ and 1.26M☉, 3.34R☉ respectively. The cool and less massive secondary has filled its Roche lobe and it is over luminous for its mass.
