Non-LTE line formation for heavy elements in four very metal-poor stars
L. Mashonkina, G. Zhao, T. Gehren +6
Stellar parameters and abundances of Na, Mg, Al, K, Ca, Sr, Ba, and Eu are determined for four very metal-poor stars (-2.66 < [Fe/H] < -2.15) based on non-LTE line formation and an…

NeIII/OII as an oxygen abundance indicator in the HII regions and HII galaxies
F. Shi, G. Zhao, Y. C. Liang
To calibrate the relationship between Ne3O2 (Ne3O2 = log(\neiii/\oii)) and oxygen abundances, we present a sample of 3000 $\hii$ galaxies from the S…
