Abstract

We present phaseresolved circular polarization measurements of the rotating magnetic white dwarf KPD 0253+5052 . A new and more accurate period of h for KPD 0253+5052 could be determined by measuring the broadband polarization in the H and H lines derived from medium resolution (about 5Å FWHM) spectropolarimetric data at different phases.

Key words: stars: individual: KPD 0253+5052 stars: white dwarfs
