Eclipsing binary EW system
« on: January 29, 2017, 02:17:01 AM »
Hi everybody, is there a contact eclipsing binary system (variable star EW type) model available?

W Ursae Majoris-type eclipsing variables. These are eclipsers with periods usually shorter than 1 day, consisting of ellipsoidal components almost in contact and having light curves for which it is impossible to specify the exact times of onset and end of eclipses. The depths of the primary and secondary minima are almost equal or differ insignificantly. Light amplitudes are usually <0.8 mag. in V. The components generally belong to spectral types F-G and later.
