Non-LTE line formation of Fe in late-type stars - I. Standard stars with 1D and [3D] model atmospheres

Bergemann, Maria; Lind, Karin; Collet, R; Magic, Zazralt; Asplund, Martin

Description

We investigate departures from local thermodynamic equilibrium (LTE) in the line formation of Fe for a number of well-studied late-type stars in different evolutionary stages. A new model of the Fe atom was constructed from the most up-to-date theoretical and experimental atomic data available so far. Non-LTE (NLTE) line formation calculations for Fe were performed using 1D hydrostatic marcs and mafags-os model atmospheres, as well as the spatial and temporal average stratifications from full...[Show more]
