Diversity of morphology of type II spicules in MURaM-ChE simulations

Sanghita Chandra, Robert Cameron, Damien Przybylski +1

Spicules are ubiquitous, small-scale features in the solar atmosphere, exhibiting a jet-like appearance most clearly identified by their apparent motion in off-limb observations. W…

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…

Self-consistent numerical simulations for the formation and dynamics of solar prominences

Lisa-Marie Zessner, Robert H. Cameron, Sami K. Solanki +1

Solar prominences are cool and dense plasma structures floating in the hot solar corona. They are ubiquitous features in the solar atmosphere, but their formation mechanism is stil…

Ca ii 854.2 nm in an enhanced network region simulated with MURaM-ChE

P. A. Ondratschek, D. Przybylski, H. N. Smitha +2

The Ca ii 854.2 nm line is widely used to study the chromosphere of the Sun. In the quiet Sun, the spatially averaged line profile shows a red asymmetry and a redshift of the line…

Simulations of facular magnetic fields on cool stars I: Main sequence stars with solar metallicity

Tanayveer Singh Bhatia, Robert H. Cameron, Sami K. Solanki +4

Stellar convection in the presence of magnetic field affects the emergent intensity, as well as the structure and evolution of cool main-sequence dwarfs. We aim to understand the e…

Statistical properties of spicules in MURaM-ChE

Sanghita Chandra, Robert Cameron, Damien Przybylski +1

Numerical simulations of the solar chromosphere have progressed towards reproducing spicules, which are transient features observed at the solar limb using spectral lines such as H…
