Chemical diversity among A-B stars with low rotational velocities: non-LTE abundance analysis
L. Mashonkina, T. Ryabchikova, S. Alexeeva +2
We present accurate element abundance patterns based on the non-local thermodynamic equilibrium (non-LTE, NLTE) line formation for 14 chemical elements from He to Nd for a sample o…
Mono-enriched stars and Galactic chemical evolution -- Possible biases in observations and theory
Camilla Juul Hansen, Andreas Koch, Lyudmila Mashonkina +9
A long sought after goal using chemical abundance patterns derived from metal-poor stars is to understand the Galactic chemical evolution (GCE) and to pin down the nature of the fi…
Influence of Collisions with Hydrogen on Titanium Abundance Determinations in Cool Stars
T. M. Sitnova, S. A. Yakovleva, A. K. Belyaev +1
We performed the non-local thermodynamic equilibrium (non-LTE) calculations for Ti I-II with the updated model atom that includes quantum-mechanical rate coefficients for inelastic…
