Scientific paper

Recent time-resolved spectrophotometric observations of VV Pup are presented. On the basis of the line profile behavior the dynamical solution of the system is revised and improved system parameters are obtained. The H-alpha line profile is analyzed with the Doppler tomography technique aiming to identify the region of emission line formation and to investigate the main characteristics of the Doppler images of classical polars. The detection of the stream and the absence of an accretion disk is conspicuous in the derived image. From the flux distribution in the map and the theoretical location of the steam, column, and the stellar components we conclude that most (75%) of the H-alpha flux is produced in the upper stream and in the secondary star surface. A small contribution for the Balmer lines should come from the magnetic funneled matter. An upper limit for the magnetospheric radius of approximately 3 1010 cm is suggested.
