description A surface brightness analysis on the photometric and radial-velocity data of EU Tau presented by Gieren et al. (1989) is presented. The stellar radius and distance are determined with a 5 percent precision. The radius and distance results are used to establish the fundamental stellar parameters, including luminosity, mass, effective temperature, and binary status. The results strongly suggest that EU Tau is pulsating in the radial first overtone mode. (R.B.)
