| Abstract: |
We review the power of Doppler tomography for detailed investigations of polars (magnetic cataclysmic binaries without accretion disks). Using high-resolution spectroscopy in combination with tomography as an analytic tool, the structure and extent of the accretion flows and accretion curtains in the binaries can be uncovered, and the irradiated and non-irradiated parts of the mass-donating secondary stars can be made visible. In addition we show how basic system parameters like the binary inclination and the mass ratio can be addressed by tomography. |
