Abstract: The semi-detached eclipsing binary system VW Hydrae (P = 2.70 days) has been analysed using the Wilson-Devinney program, on the basis of light curves obtained in the GENEVA seven-colour photometric system, and radial velocity curves for both components measured with the cross-correlation technique. The physical and orbital parameters have been determined through a self-consistent simultaneous solution of light curves in seven colours and of the radial velocity curves of both components. The effective temperature of the primary component is determined from the photometric analysis, T-eff1= 10, 650 +/- 200 K. It is shown that this value can be very well determined, despite the fact the primary eclipse is partial, by the use of colour indexes, as e.g. [B-2 - V-1](0).
