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 power law for the TRAPPIST-1 flare distribution across four orders of magnitude in energy
Valeriy Vasilyev, Alexander I. Shapiro, Nadiia Kostogryz +10
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets' high-energy irradiation environments, with consequences for atmospheric chemis…
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…
Probing chromospheric fine structures with a Hα proxy using MURaM-ChE
Sanghita Chandra, Robert Cameron, Damien Przybylski +3
H observations of the solar chromosphere reveal dynamic small-scale structures known as spicules at the limb and rapid blue and red shifted excursions (RBEs/RREs) on-disk. We w…
3D Radiative MHD Simulations of Starspots II: Large-scale Structure
Tanayveer Singh Bhatia, Mayukh Panja, Robert Cameron +1
We compute realistic 3D radiative MHD near-surface models of starspots with substantial penumbrae on cool main-sequence stars using the MURaM simulation code. This work is an impro…
