Period variations of the late type contact binaries YY Eri and AE Phe: how to use light curves outside minimum.

MACERONI C. and VAN'T VEER F.

Abstract (from CDS):

We present and compare minimum times, computed for light curves of the W Uma type binaries YY Eri and AE Phe. Two different methods are used: the Leiden method formulated by Kwee & van Woerden and the light curve synthesis method developed by Wilson & Devinney. It is shown that the latter gives more and better information, and is even capable to extract the times of conjunction. Its application requires a complete analysis of the parameters of the system, including the surface inhomogeneities. The observations are available in electronic form.
