HE 1045-0908: a new magnetic DA white dwarf with a distinctive Zeeman line splitting pattern.

Abstract (from CDS):

We report the discovery of a magnetic DA white dwarf within the Hamburg/ESO objective prism survey for bright quasars. The new magnetic DA HE 1045-0908 was found by automated search techniques and classified as QSO candidate. Subsequent spectroscopy with EFOSC at the ESO 3.6m telescope showed that Hα is a triplet, while Hβ and Hγ are split in a distinctive way into several Zeeman components. A model atmosphere analysis yields Teff= 9200 ±500 K, a polar field strength of 31 ±2 MG, and a dipole inclination of 5deg+15deg-5deg, i.e. a nearly equator-on view.
