Outflow from and asymmetries in the nebula around the LBV candidate Sk-69 279

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.
