A test of the optimization techniques for contact binaries photometric analysis [PDF]

, 2022
Light curve analysis of contact binaries are presented and compared with previous cross-correlations velocity data. The critical parameter q (mass-ratio) obtained by a grid technique is confronted with its spectroscopic value. For total eclipsing systems,

Physical parameters of components in close binary systems - VII

, 2010
We present results of the modelling of multicolour light curves of 10 contact binary systems: V376 And, V523 Cas, CC Com, BX Dra, FG Hya, UZ Leo, XY Leo, AM Leo, EX Leo and RT LMi. The solutions resulted in a contact configuration for all systems.

Period and light-curve study of the contact eclipsing binary V523 Cas

New Astronomy, 2016
Abstract CCD photometry of the eclipsing W Uma binary system V523 Cas in U, B, V and RC filters was carried out during eight nights in 2012. The physical and geometrical parameters of this system are obtained. A possible pulsation period of one of the components is obtained by analyzing the residuals of the ephemeris light curve.

Absolute dimensions of the close binary systems V453 Monocerotis and V523 Cassiopeiae

Astrophysics and Space Science, 2009
We present multi-colour CCD observations of the low-temperature contact binaries, V453 Mon and V523 Cas. Their light curves are modelled to determine a new set of stellar and orbital parameters. Analysis of mid-eclipse times yields a new linear ephemeris
