Observing the Accretion Stream in Polars
  We have developed a 3D computer model of polars which includes the accretion stream, the accretion column, the secondary star, and the white dwarf. Each component is represented by a fine grid of surface elements. With brightness values attributed to each surface element, this model generates synthetic light curves of the various components. As a first application, we present our simulated light curves of the accretion stream, fitted to high-speed HST spectroscopy of the eclipsing polar UZ Fornacis by the means of an evolution strategy.
