Are there spots on magnetic white dwarfs?
The temporal variation of the circular polarization observed in the magnetic white dwarf G195-19 is interpreted in terms of an oblique rotator model. The peculiar behavior observed in red light strongly suggests the presence of a spot on the surface of this star. A model based on this assumption is found to be consistent with observations.
