Chemical composition of metal-poor stars in Coma Berenices ultra-faint dwarf galaxy as a proxy to individual chemical enrichment events
Tatyana Sitnova, Lyudmila Mashonkina, Andrey Tatarnikov +3
We present NLTE abundances and atmospheric parameters for three metal-poor stars ([Fe/H]<-2) in Coma Berenices ultra-faint dwarf galaxy (UFD). The derived results are based on new…

A NLTE line formation for neutral and singly-ionised calcium in model atmospheres of B-F stars
Tatyana Sitnova, Lyudmila Mashonkina, Tatyana Ryabchikova
We present non-local thermodynamic equilibrium (NLTE) line formation calculations for Ca I and Ca II in B-F stars. The sign and the magnitude of NLTE abundance corrections depend o…
