candidate S 119

Abstract.
We present an analysis of the kinematic and
morphological structure of the nebula around the LMC LBV
candidate S 119. On HST images, we find a predominantly spherical
nebula which, however, seems to be much better confined in its
eastern hemisphere than in the western one. The filamentary
western part of the nebula is indicative of matter flowing out of
the nebula's main body. This outflow is even more evidenced
by our long-slit echelle spectra. They show that, while most of
the nebula has an expansion velocity of 25.5 km/s, the
outflowing material reaches velocities of almost
140 km/s relative to the systemic one. A ROSAT HRI image
shows no trace of S 119 and thus no indications of hot or shocked
material.
