| Abstract: |
It is still an unresolved question how much AGB stars can contribute
to the overall gas and dust enrichment processes in the interstellar
medium within galaxies.
We start tackling this problem by using, as our test case, observational
data from the Large Magellanic Cloud (LMC), from which we obtain the
global gas and dust budget.
The photometric data from the LMC is obtained with the Spitzer Space
Telescope.
We have established an infrared colour classification scheme to select
AGB stars, based on spectroscopically identified AGB stars.
We further confirm a correlation between the Spitzer colour and
mass-loss rate, which leads to a measurement of the total mass-loss
rate from the entire AGB population in the LMC.
Indeed, AGB stars are an important source of gas and dust. |
