Abstract
The first reliable radial velocity curves for RZ Tau have been obtained. Combined with new light curve (LC) data, simultaneous Roche-based light curve analyses have been carried out using the 2003 version of the Wilson-Devinney code. New values for the masses and radii have been obtained: M1 = 1.53 (4) Mʘ, M2 = 0.57 (2) Mʘ, and R1 = 1.50 (4) Rʘ, R2 = 0.99 (2) Rʘ. Although there is a multitude of spectral classifications listed in the literature, the classification of F0 from Struve et al. (1950) is shown to be the most reliable. On the basis of the latter, the most likely luminosities are L1 = 4.97 (44) Lʘ and L2 = 2.11 (19) Lʘ. Additional modelling was carried out using the same RV data, but with LC data (binned and unbinned) from Binnendijk (1963); the results were substantially the same except that they favoured slightly later spectral sub-classes.
