UV observations of 4 stars in the Carina Nebula region have been obtained with STIS at a resolution of R ~ 110,000. All four stars demonstrate numerous high velocity components extending over ranges ~ ± 200 km/sec. In particular two observations of the star CPD -59 2603 have been obtained 22 months apart and demonstrate substantial variations in the intensities of the high velocity components of Mg II 2796.35, 2803.53 and Mg I 2852.96 lines. The origin of the variations is discussed. Furthermore, there is a marked similarity in the shape of the absorption features with those seen in narrow-lines QSO systems, which may shed light on the origin of these features.
This work was supported by NASA through the STIS GTO funding.
