Parallel sessions

The lower solar atmosphere hosts a wealth of complex plasma dynamics associated with intricate and rapidly evolving magnetic elements, giving rise to a wide variety of observed phenomena, spanning the quiet Sun, coronal holes and active regions. Observational, analytical and numerical investigation of the formation and evolution of these sophisticated flows and the small-scale magnetic field, is essential to understanding the broader implications of these phenomena, with respect to mass and energy transfer throughout the solar atmosphere. With the dawn of unprecedented, high-resolution ground-based observations (notably DKIST) and, furthermore, with recent advances in novel space-based observatories for exploration of the lower solar atmosphere (notably Solar Orbiter), we are entering decades worth of bespoke observations that will open up a new, unexplored window into the detailed physics of the solar photosphere and chromosphere at spatial and temporal scales never before seen. We can look forward to fruitful new exploration of fundamental processes such as the creation and support of magnetic fields, stability and interconnectivity of rotational flow vortices, interactions of magnetic bright points, wave generation in spicules and magnetic flux tubes with jets, emergence of small flux ropes, formation of sunspot umbra and penumbra and many more. Such observations will allow us to both develop and improve mathematical models used to study plasma turbulence, coherent structures and interactions between flows and magnetic fields at the smallest scales, within the photosphere and chromosphere, the powerhouse of the solar corona. This session will provide an excellent opportunity to discuss current and future observing synergies for multi-instrument, high-resolution observations and development of advanced numerical MHD simulations describing the many phenomena at the level of the photosphere and chromosphere in both quiet Sun and active regions. The participants will have a platform to advertise their DKIST and Solar Orbiter related solar science, especially in the following topics:

Small-scale photospheric magnetic fields;
Coherent plasma motions (e.g., vortices, source / sink type motions and laminar flows; spicules, swirls, ellerman bombs, magnetic bright points, sunspot structures/flows)
Energy transport between lower and upper solar atmosphere layers;
Turbulent plasma processes.
