| Abstract: |
The FUSE spectra of cataclysmic variables containing magnetic white dwarfs show a variety of properties. Our FUSE spectra of AR UMa, YY Dra and SDSSJ080908+3814 cover a wide range of magnetic fields from the highest known field in AR UMa to the low fields in the non-spin locked sources YY Dra and the SDSS object. These objects also encompass a large range of viewing angles of the poles since the pole is close to the spin axis in AR UMa whereas YY Dra has two accreting poles near the equator that are separated by 180°. The unique capabilities of FUSE allows us to delineate the accretion parameters in these systems from its access to high temperature regions of emission and the use of time-resolved spectra. In AR UMa, the FUSE spectra show Zeeman components that are sensitive to the field strength and dipole structure. In YY Dra, the time resolved light curves allow us to model the temperature and size of the two accretion areas on the white dwarf. |
