Non-LTE analysis of K I in late-type stars
Henrique Reggiani, Anish M. Amarsi, Karin Lind +7
Older GCE models predict [K/Fe] ratios as much as 1 dex lower than those inferred from stellar observations. Abundances of potassium are mainly based on analyses of the 7698 re…

Excitation and charge transfer in low-energy hydrogen atom collisions with neutral carbon and nitrogen
A. M. Amarsi, P. S. Barklem
Low-energy inelastic collisions with neutral hydrogen atoms are important processes in stellar atmospheres, and a persistent source of uncertainty in non-LTE modelling of stellar s…

Two-dimensional non-LTE \ion{O}{I} 777\,nm line formation in radiation hydrodynamics simulations of Cepheid atmospheres
V. Vasilyev, A. M. Amarsi, H. -G. Ludwig +1
Oxygen abundance measurements are important for understanding stellar structure and evolution. Measured in Cepheids, they further provide clues on the metallicity gradient and chem…
