International Conference on Binaries: In Celebration of Ron Webbink's 65th Birthday, Mykonos, Greece, 22 - 25 June 2010, vol.1314, pp.210-211
We present a study on magnetic cataclysmic variables (polars) using the collected data from the literature. These parameters (mass, radius, magnetic field intensity, mass transfer rate, etc.) and the relations between them are important to understand their nature, to explain the observed properties of them and to test the current evolutionary models.
