W Vir: temperature, radius and radial velocity determinations from B, V photometry [Observed: 16 observing sessions from 27 April to 20 July 2005]
V and B magnitudes measurements are obtained for this Population
II Cepheid pulsating star. They are used to compute the variations of
temperature, radius and radial velocity.
The results are compared with
direct measurements from spectroscopy.
