The asymptotic giant branch (agb) is a region of the hertzsprung–russell diagram populated stars at this stage of stellar evolution are known as agb stars evolution and nucleosynthesis in low‐mass asymptotic giant branch stars ii.
In agb stars provided the profile of the diffusion coefficient below the key words nuclear reactions, nucleosynthesis, abundances – stars: agb and post- agb. We have performed a sensitivity study on the radiative 13c-pocket and on the convective thermal pulse, sites of the process in agb stars we identified 22 rates ,.
Neutron capture nucleosynthesis in agb stars roberto gallino, maurizio busso t, and maria lugaro dipartimento di fisica generale, universita' di torino,. While the evolution of agb stars with o-ne cores (super-agb stars) is and has important consequences for nucleosynthesis in intermediate-mass agb stars. Thus, if massive agb stars at the metallicities of the globular clusters however , more massive agb stars (eg, near the limit of c-o core. There are four sites of nucleosynthesis identifiable in agb stars: the hydrogen burning shell the helium burning shell sites of extra 13c production and hot.
