Outflow from and asymmetries in the nebula around the LBV candidate Sk-69deg279.

WEIS K. and DUSCHL W.J.

Abstract (from CDS):

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 it resembles 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 and poses the question: in how far are outflows out of expanding LBV nebulae a general property of such nebulae - at least during some phases of their evolutions.
