Scientific paper

We present results of the modelling of multicolour light curves of 10 contact binary systems: V376And, V523Cas, CCCom, BXDra, FGHya, UZLeo, XYLeo, AMLeo, EXLeo and RTLMi. The solutions resulted in a contact configuration for all systems. We found only FGHya and UZLeo to be in deep contact, the latter almost filling the outer critical lobe. The absolute parameters of the components have been determined with an accuracy of about a few per cent based on combined photometric and radial velocity curves, enlarging the sample of systems to 58 for which the physical parameters have been obtained in a uniform way. All but three systems (BXDra, AMLeo and RTLMi) show asymmetries and peculiarities in the observed light curves, interpreted as resulting from their magnetic activity.
