Abstract
High and low resolution spectra of the spectroscopic triple star θ Muscae were studied for time-variability. Within 7 min no variations were found in the low resolution data. On a time scale of 8 days and longer, variations in the P Cygni profiles of the resonance lines occur. These may be explained as variable mass loss from the system, or as aspect effects in an asymmetric wind flow.
