[113.12] Colliding Winds in the WR+OB Binary \theta Mus (WR 48)

Spectra, providing full phase coverage, of the 19 d WC6+OB binary \theta Mus (WR 48, HD 113904), have been obtained and show dramatic variations of the C {\sc iii} \lambda5696 emission line profile. We have modeled these line profile variations assuming the winds from the WR star and its close OB companion are colliding and forming a shock region from which extra emission originates.
