Outflow from and asymmetries in the nebula
around the LBV candidate Sk-69 279
Astronomy and Astrophysics, 393, 503-510 (2002),
Abstract.
We present and discuss new long-slit Echelle spectra of
the LMC LBV candidate Sk-69 279 and put them in context with previous
images and spectra. While at first glance a simple spherically
expanding symmetric shell, we find a considerably more complex
morphology and kinematics. The spectra indicate that
morphologically identified deviations from sphericity are outflows
of faster material out of the main body of Sk-69 279. The morphological
as well as the kinematic similarity with other LBV nebulae makes
it likely that Sk-69 279 is an LBV candidate, indeed, and poses the
question in how far outflows out of expanding LBV nebulae are a
general property of such nebulae - at least during some phases of
their evolutions.
