Line profile variation in delta Orionis A, IOTA Orionis A, and 15 Monocerotis.
Abstract
The results of a monitoring program with IUE and Einstein are presented for three stars, δ Ori A, ι Ori A, and 15 Mon. Line profile variability is observed in the UV profiles accessible to IUE and the relation between the variation in the different ions suggests that the ionization level is varying in the winds of these stars. This is consistent with Einstein observations of soft X-ray variability for two of the stars.
