Cross-Field Diffusion Effects on Particle Transport in a Solar Coronal Flux Rope
Edin Husidic, Nicolas Wijsen, Luis Linan +3
Solar energetic particles (SEPs) associated with solar flares and coronal mass ejections (CMEs) are key agents of space weather phenomena, posing severe threats to spacecraft and a…
Efficient magnetohydrodynamic modelling of the time-evolving corona by COCONUT
Haopeng Wang, Stefaan Poedts, Andrea Lani +6
Compared to quasi-steady-state corona models that are constrained by a time-invariant magnetogram over a CR period, time-evolving corona models driven by time-varying photospheric…
Density-gradient-driven drift waves in the solar corona
Michaela Brchnelova, MJ Pueschel, Stefaan Poedts
It has been suggested that under solar coronal conditions, drift waves may contribute to coronal heating. Specific properties of the drift waves to be expected in the solar corona…
