1.5D investigation of the Hanle effect in the Ca I 4227 line using partial frequency redistribution. Comparison of synthetic Stokes profiles in Bifrost and MURaM-ChE rMHD models
Devang Agnihotri, L. S. Anusha, D. Przybylski +2
Modeling scattering polarization in the Ca I 4227 Å line is important for diagnosing chromospheric magnetic fields. We investigate the relative influence of formation heights and m…
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…
A single frequency approach to nonequilibrium modeling of the chromosphere
W. Ruan, D. Przybylski, R. Cameron +1
The solar chromosphere is a region where radiation plays a critical role in energy transfer and interacts strongly with the plasma. In this layer, strong spectral lines, such as th…
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…
A self-consistent 3D MHD model producing a solar blowout jet
Yajie Chen, Hardi Peter, Damien Przybylski +2
Context. Solar blowout jets are a distinct subclass of ubiquitous extreme-ultraviolet (EUV) and X-ray coronal jets. Aims. Most existing models of blowout jets prescribe an initial…
Simulations of structured upflows from plumes and their connection to the solar wind
Kamlesh Bora, Lakshmi Pradeep Chitta, Yajie Chen +3
Small-scale transient jetlet activity and associated upflows from coronal hole plumes are potential sources of the solar wind. To elucidate the magnetic origins and driving mechani…
