Luminous Blue Variables in the Large Magellanic Cloud
Abstract
We propose to gather radio morphological and spectral information on four LBVs in the Large Magellanic Cloud. The aim of this project is to fully characterize the radio properties of the LBVs in LMC and compare them with results from the Galactic sample. This comparison will be extended to the mid-IR, taking advantage of the new released SAGE/SST dataset, to point out if any systematic differences exist between gas (as traced by radio emission) and dust (as traced by mid-IR) content. This would also point out different kinds of interaction of such components, eventually indicating the role playing by the dust in the formation, shaping and expansion velocity of such ejecta. We, in fact, expect dust production to be less efficient in a lower metallicity environment such as the LMC.
