Query: An outflow from the nebula around the LBV candidate S 119   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.
