Non-LTE line formation for iron group elements. II. Fe VI.

Abstract

A non-LTE line formation calculation for Fevi is presented. The data for radiative bound-bound transitions which have been derived as part of this work are described and their accuracy is evaluated. The theoretical non-LTE spectrum of Fevi is compared to an IUE spectrum of Feige 67. An iron abundance of approximately ten times the solar value is derived for this object. This value is consistent with the result based on Fev. Implications of this value of the iron abundance are discussed.
