Three-dimensional non-LTE radiative transfer effects in Fe I lines IV. Line formation at high spatial resolution
R. Holzreuter, H. N. Smitha, S. K. Solanki
In the first three papers of this series, we investigated the formation of photospheric neutral iron lines in different atmospheres ranging from idealised flux tube models to compl…

Influence of NLTE effects in Fe I lines on inverted atmosphere II. 6301 A and 6302 A lines formed in 3DNLTE
H. N. Smitha, R. Holzreuter, M. van Noort +1
This paper forms the second part of our study on how the neglect of NLTE conditions in the formation of Fe I 6301.5 A and the 6302.5 A lines influences the atmosphere obtained by i…

The influence of NLTE effects in Fe I lines on an inverted atmosphere I. 6301 A and 6302 A lines formed in 1D NLTE
H. N. Smitha, R. Holzreuter, M. van Noort +1
Ultraviolet over-ionisation of iron atoms in the solar atmosphere leads to deviations in their level populations from the Saha-Boltzmann statistics. This causes their line profiles…
