Exploring The Mass-Loss History and The Dust Content in Circumstellar Nebulae Around Luminous Blue Variable Stars
Millennium Institute of Astrophysics, Santiago, Chile
The physical mechanism responsible for high mass-loss in luminous blue variable stars (LBVs) is still poorly understood. The possibility that it is independent of metallicity is of paramount importance to LBVs in the metal-poor Universe. Our approach to investigate this possibility is to study LBVs in different environments and to use multiwavelength observations to resolve their nebulae. These contain the fingerprints of their mass-loss, as shown here by the galactic example G79.29+0.46. I also present our pilot study of objects in the Magellanic Clouds (MCs), where a paucity of data existed so far.
