Low temperature Rosseland opacities with varied abundances of carbon and nitrogen
Michael T. Lederer, Bernhard Aringer
We attempt to produce low temperature opacity data incorporating the effects of varied abundances of the elements carbon and nitrogen. For our temperature range of interest, molecu…
AGB stars of the intermediate-age LMC cluster NGC 1846 II. Dredge up along the AGB
T. Lebzelter, M. T. Lederer, S. Cristallo +3
Aims: We investigate the change in the surface abundance of C during the evolution along the AGB, aiming to constrain third dredge-up models. Methods: High-resolution, near-…
Low temperature mean opacities for the carbon-rich regime
Michael T. Lederer, Bernhard Aringer
Asymptotic Giant Branch (AGB) stars undergo a change in their chemical composition during their evolution. This in turn leads to an alteration of the radiative opacities, especiall…
Low-mass lithium-rich AGB stars in the Galactic bulge: evidence for Cool Bottom Processing?
Stefan Uttenthaler, Thomas Lebzelter, Sara Palmerini +3
Context: The stellar production of the light element lithium is still a matter of debate. Aims: We report the detection of low-mass, Li-rich Asymptotic Giant Branch (AGB) stars loc…
Molecular opacities for low-mass metal-poor AGB stars undergoing the Third Dredge Up
S. Cristallo, O. Straniero, M. T. Lederer +1
The concomitant overabundances of C, N and s-process elements are commonly ascribed to the complex interplay of nucleosynthesis, mixing and mass loss taking place in Asymptotic Gia…
