Description
Visual and infrared light curves of the noncontact, short period, close
binary system UR Tauri were obtained in 1992 November. A new ephemeris
of the binary is given using the times of minima inferred from all the
observations of the system to date. New light and photometric data from
the analysis of the B, V and J,K light curves via the Wilson-Devinney
code are also given, resulting in a "near-contact" binary model for the
system. The analysis of the colors of UR Tauri shows that the primary
component's spectral type must be about A9 V, instead of AS V according
to a recent spectroscopic classification.
