The heavy-element abundances of AGB stars and the angular momentum conservation model of wind accretion for barium stars
Y. C. Liang, G. Zhao, B. Zhang
Adpoting new s-process nucleosynthesis scenario and branch s-process path, we calculate the heavy-element abundances and C/O ratio of solar metallicity 3M_sun TP-AGB stars. The evo…

Sc and Mn abundances in disk and metal-rich halo stars
P. E. Nissen, Y. Q. Chen, W. J. Schuster +1
Sc and Mn abundances are determined for 119 F and G main-sequence stars with -1.4 < [Fe/H] < +0.1, representing stars from the thin disk, the thick disk and the halo. The results i…
