Magnetic Fields of White Dwarfs

We present results of Zeeman CCD measurements of DA white dwarfs carried out with the 6-m telescope of the Special Astrophysical Observatory in 1995 2000. The accuracy of the measurements ranges from 0.5 to 15 kG. Magnetic fields were detected in three of the 26 observed white dwarfs. We have confirmed the existence of magnetic fields on WD 1953-011 (B e=28±6 kG) and 40 Eri B (B e(min)=-2.8 kG, B e(max)=1.8 kG). The data are discussed in the context of a statistical study of the occurrence of magnetic white dwarfs.
