Updated stellar yields from asymptotic giant branch models

An updated grid of stellar yields for low- to intermediate-mass thermally pulsing asymptotic giant branch (AGB) stars is presented. The models cover a range in metallicity <it>Z</it>= 0.02, 0.008, 0.004 and 0.0001, and masses between 1 and 6 M<inf>⊙</inf>. New intermediate-mass (<it>M</it>≥ 3 M<inf>⊙</inf>) <it>Z</it>= 0.0001 AGB models are also presented, along with a finer mass grid than used in previous studies. The yields are computed using an updated reaction rate network that includes the latest NeNa and MgAl proton capture rates, with the main result that between ∼6 and 30 times less Na is produced by intermediate-mass models…
