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…
A Science Gateway for Atomic and Molecular Physics
Barry I. Schneider, Klaus~Bartschat, Oleg Zatsarinny +7
We describe the creation of a new Atomic and Molecular Physics science gateway (AMPGateway). The gateway is designed to bring together a subset of the AMP community to work collect…
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…
Electron-impact excitation and ionization of atomic calcium at intermediate energies
Oleg Zatsarinny, Henry Parker, Klaus Bartschat
We present a comprehensive study of electron collisions with calcium atoms by using the convergent \emph{B}-spline \emph{R}-matrix method. Elastic, excitation, and ionization cross…
Inelastic O+H collisions and the OI 777nm solar centre-to-limb variation
A. M. Amarsi, P. S. Barklem, M. Asplund +2
The OI 777 nm triplet is a key diagnostic of oxygen abundances in the atmospheres of FGK-type stars; however it is sensitive to departures from local thermodynamic equilibrium (LTE…
Inelastic e+Mg collision data and its impact on modelling stellar and supernova spectra
P. S. Barklem, Y. Osorio, D. V. Fursa +4
Results of calculations for inelastic e+Mg effective collision strengths for the lowest 25 physical states of Mg I (up to 3s6p 1P), and thus 300 transitions, from the convergent cl…
