Non-LTE abundance analysis of A-B stars with low rotational velocities. II. Do A-B stars with normal abundances exist?
A. M. Romanovskaya, T. A. Ryabchikova, Yu. V. Pakhomov +2
We present chemical composition and fundamental parameters (the effective temperature, surface gravity and radius) for four sharp-lined A-type stars Gem (HD 41705), o Peg (HD 2…

1D non-LTE corrections for chemical abundance analyses of very metal-poor stars
L. Mashonkina, Yu. Pakhomov, T. Sitnova +3
Detailed chemical abundances of very metal-poor (VMP, [Fe/H] < -2) stars are important for better understanding the First Stars, early star formation and chemical enrichment of gal…
