Studying Asymptotic Giant Branch Stars in the JWST Era

Studying Asymptotic Giant Branch Stars in the JWST Era

We explore the potential offered by the incoming launch of the James Webb Space Telescope, to study the stars evolving through the asymptotic giant branch (AGB) phase. To this aim we compare data of AGB stars in the Large Magellanic Cloud, taken with the IRS spectrograph, with the results from model...
