| Abstract: |
Mass loss is one of the fundamental properties of Asymptotic Giant
Branch (AGB) stars, and through the enrichment of the interstellar
medium, AGB stars are key players in the life cycle of dust and gas
in the Universe. However, a quantitative understanding of the
mass-loss process is still largely lacking, in particular its
dependence on metallicity. Direct measures of mass-loss
rates in AGB stars of the Magellanic Clouds (MCs) are limited
to samples of
∼ 100 stars (e.g. Groenewegen et al. 2009). Estimates on larger samples
of stars are, to date, based on empirical relations between mass-loss
rates and colors in the mid-IR (e.g. Matsuura et al. 2009). Our project
aims at a direct measure of mass-loss rate in all AGB stars in the
MC system. |
