Abstract

We comment on the applicability of the stationary line argument recently used by Jordan et al. (1998) to account for the unusual absorption features in the observed optical spectra of GD 229. Moreover, we provide an alternative explanation based upon the existence of neutral and singly ionized atomic helium atoms as the main elements comprising the atmosphere of this magnetized white dwarf star. :.
