Non-equilibrium hydrogen ionization in 2D simulations of the solar atmosphere
J. Leenaarts, M. Carlsson, V. Hansteen +1
The ionization of hydrogen in the solar chromosphere and transition region does not obey LTE or instantaneous statistical equilibrium because the timescale is long compared with im…
Dynamic Fibrils are driven by Magnetoacoustic Shocks
V. H. Hansteen, B. de Pontieu, L. Rouppe van der Voort +2
The formation of jets such as dynamic fibrils, mottles, and spicules in the solar chromosphere is one of the most important, but also most poorly understood, phenomena of the Sun's…
Multi-level 3D non-LTE computations of lithium lines in the metal-poor halo stars HD140283 and HD84937
M. Asplund, M. Carlsson, A. Botnen
The lithium abundances in metal-poor halo stars are of importance for cosmology, galaxy evolution and stellar structure. In an attempt to study possible systematic errors in the de…
