Buoyant magnetic flux tubes as a site for 26Al production in AGB stars

, 2006
We address the diffusive circulation of matter occurring in AGB stars above the H-burning shell, which triggers the production of p-rich isotopes like 13C and 17O and of the unstable nucleus 26Al, observed in presolar grains and in Early Solar System ...

VLTI/MIDI Large Program: AGB Stars at Different Spatial Scales

, 2015
We have observed a sample of Asymptotic Giant Branch (AGB) stars from the Herschel Mass-loss of Evolved StarS (MESS) program with the VLTI MID infrared Interferometric instrument (MIDI).

The Circumstellar (CO)-C-12/(CO)-C-13 Ratio in AGB Stars of Different Chemical Type

, 2015
We have investigated the evolution of the C-12/C-13 ratio along the AGB through the circumstellar isotopologue (CO)-C-12/(CO)-C-13 abundance ratio for a significant number of M-, S-, and C-type AGB stars.
