Mg II h&k spectral line properties computed using 3D radiative transfer in an enhanced network region simulated with the MURaM-ChE code
P. Ondratschek, D. Przybylski, H. N. Smitha +3
The Mg II h&k lines form in the middle to upper chromosphere and are well-suited to study the structure of the chromosphere. However, the details of their formation in the solar ch…
The magnetic sensitivity of the Ca II H and K lines
M. Kriginsky, J. Leenaarts, J. de la Cruz Rodriguez +2
The solar chromosphere is a transition layer between the cool, dense photosphere and the hot, rarefied corona. This boundary region plays a key role in regulating energy transport…
Solar carbon abundance from 3D non-LTE modelling of the diagnostic lines of the CH molecule
Richard Hoppe, Maria Bergemann, Philipp Eitner +5
The spectral lines of the CH molecule are a key carbon (C) abundance diagnostic in FGKM-type stars. These lines are detectable in metal-rich and, in contrast to atomic C lines, als…
Science Requirement Document (SRD) for the European Solar Telescope (EST) (3rd Edition, December 2025)
Rolf Schlichenmaier, Luis R. Bellot Rubio, Manuel Collados Vera +31
The European Strategy Forum on Research Infrastructures (ESFRI) included the European Solar Telescope (EST) as an ESFRI Project in its 2016 Roadmap and confirmed this status in 202…
Structure and dynamics of the internetwork solar chromosphere: results of a small-scale dynamo simulation
D. Przybylski, R. Cameron, S. K. Solanki +3
The heating and structure of the solar chromosphere depends on the underlying magnetic field, among other parameters. The lowest magnetic flux of the solar atmosphere is found in t…
High flow speeds and transition-region like temperatures in the solar chromosphere during flux emergence
J. Leenaarts, M. van Noort, J. de la Cruz RodrÃguez +7
Context: Flux emergence in the solar atmosphere is a complex process that causes a release of magnetic energy as heat and acceleration of solar plasma at a variety of spatial scale…
