NLTE study of scandium in the Sun
H. W. Zhang, T. Gehren, G. Zhao
We investigate the formation of neutral and singly ionized scandium lines in the solar photospheres. The research is aimed derive solar (Sc) values for scandium l…

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…
