J/ApJ/696/797    Evolution and yields of low-mass AGB stars   (Cristallo+, 2009)

Evolution, nucleosynthesis, and yields of low-mass asymptotic giant branch stars at different metallicities. Cristallo S., Straniero O., Gallino R., Piersanti L., Dominguez I., Lederer M.T. <Astrophys. J., 696, 797-820 (2009)> =2009ApJ...696..797C
ADC_Keywords: Abundances ; Models ; Stars, giant Keywords: nuclear reactions, nucleosynthesis, abundances - stars: AGB and post-AGB Abstract: The envelope of thermally pulsing asymptotic giant branch (TP-AGB) stars undergoing periodic third dredge-up (TDU) episodes is enriched in both light and heavy elements, the ashes of a complex internal nucleosynthesis involving p, α, and n captures over hundreds of stable and unstable isotopes. In this paper, new models of low-mass AGB stars (2M), with metallicity ranging between Z=0.0138 (the solar one) and Z=0.0001, are presented. Main features are (1) a full nuclear network (from H to Bi) coupled to the stellar evolution code, (2) a mass loss-period-luminosity relation, based on available data for long-period variables, and (3) molecular and atomic opacities for C- and/or N-enhanced mixtures, appropriate for the chemical modifications of the envelope caused by the TDU. For each model, a detailed description of the physical and chemical evolutions is presented; moreover, we present a uniform set of yields, comprehensive of all chemical species (from hydrogen to bismuth).
