A spectroscopic study of LY Aurigae.
Abstract
Summary. Radial velocities derived from 44 spectrograms are analysed to derive new elements for LY Aurigae. These elements are: K1 = 113.0 km 1, K2= , V0=-2. , e=0.0. Using the light curve solution of McCluskey and Kondo (1973) we derive physical parameters for the system these show that it is a normal semi-detached system which has undergone case A mass-exchange. Key words: eclipsing binary - spectroscopic binary - absolute stellar dimensions - stellar evolution
