Luminous blue variable stars: exploring the mass-loss history through a multiwavelength analysis of their ejecta
Abstract
dc:descriptionThis work is focused on the multiwavelength analysis of ejecta around Luminous Blue Variable stars (LBVs), which are massive evolved stars subjected to high mass-loss episodes. In particular, the purpose of this thesis is to study the mass-loss history of a subsample of galactic and magellanic LBVs. We analysed data ranging from the mid-IR to the radio, collected with different space telescopes and interferometric and single-dish telescopes. Among the most interesting results in this work there are: the discovery of a recently formed shell in one of our sources and the evidence that galactic and magellanic objects do not differ despite the different metallicity.
