Modelling of the solar atmosphere: topics beyond the magnetohydrodynamic description
BeyondMHD
Observations of the solar atmosphere reveal many phenomena that cannot be explained by simple magnetohydrodynamic (MHD) modelling alone. In such cases, it is necessary to extend our fundamental equations beyond ideal MHD to accurately understand energy release and transport. Extensions of MHD can fundamentally change the dynamics, leading to additional energy dissipation, enhanced reconnection rates and particle acceleration. Non-MHD effects are important throughout the solar atmosphere and encompass a wide range of physical effects, including (but not limited to): partial-ionisation, kinetic effects, radiative losses, and thermal conduction. Consequences of such effects are observed and understanding the role of such effects will become increasingly important in interpreting results from the current and next generation of instruments, e.g., Parker Solar Probe, Solar Orbiter, DKIST & EST. In this session, we bring together experts in observations and numerical modelling to present consequences of, advances in, and open questions of physics beyond the standard MHD description.

Schedule:

09:00 Joerg Buechner “Diagnosing kinetic reconnection via solar radio astronomy”

09:30 Mykola Gordovskyy “Data-based MHD-particle modelling of solar flares”

09:42 Jinge Zhang “Deriving plasma parameters of large coronal magnetic loops using J-burst observation from LOFAR”

09:54 Xiaohong Li “2.5-dimensional MHD simulation of coronal rain”

10:06 Błażej Kuźma “Spatial variation of periods of ion and neutral waves in a solar magnetic arcade”

10:18 Giulia Murtas “Ionisation and recombination effects on current sheet dynamics in partially ionised plasmas”
