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…
Observational constraints on the origin of the elements II. 3D non-LTE formation of Ba ii lines in the solar atmosphere
A. J. Gallagher, M. Bergemann, R. Collet +5
Context. The pursuit of more realistic spectroscopic modelling and consistent abundances has led us to begin a new series of papers designed to improve current solar and stellar ab…
Influence of inelastic collisions with hydrogen atoms on the non-LTE line formation for Fe I and Fe II in the 1D model atmospheres of late-type stars
Lyudmila Mashonkina, Tatyana Sitnova, Svetlana A. Yakovleva +1
Iron plays a crucial role in studies of late-type stars. In their atmospheres, Fe I is the minority species and its lines are subject to the departures from LTE. In contrast, one b…
Observational constraints on the origin of the elements. I. 3D NLTE formation of Mn lines in late-type stars
Maria Bergemann, Andrew J. Gallagher, Philipp Eitner +9
Manganese (Mn) is a key Fe-group elements, commonly employed in stellar population and nucleosynthesis studies to explore the role of SN Ia. We have developed a new non-local therm…
