Session Proposal: Collisionless Shocks in Heliospheric and Astrophysical Plasmas and their Effects on Planetary Magnetospheres. (AGU25)

SH004
Collisionless Shocks in Heliospheric and Astrophysical Plasmas and their Effects on Planetary Magnetospheres.

Session ID#: 248564

Session Description:
Collisionless shock waves are ubiquitous across the universe, manifesting in diverse astrophysical plasmas, from planetary environments to supernovas. Upstream of shocks, a variable foreshock emerges, where waves interact with particles, resulting in a complex interplay which is further obfuscated by the formation of transient phenomena such as foreshock bubbles and HFAs. Downstream, a highly turbulent environment known as the sheath is formed, hosting additional transient phenomena like high-speed jets. Shocks within the Heliosphere are actively studied using spacecraft close to the Sun (Solar Orbiter, PSP), at Earth (MMS, THEMIS, Cluster) and at other planets (Cassini, Juno, Maven). In computer simulations, local (PIC) and global (Hybrid) models have been crucial in illuminating the dynamics of collisionless shock. However, despite significant progress, numerous questions remain unanswered.We welcome contributions from Heliophysics, Astrophysics, and Planetary Science communities with observational, numerical, and theoretical studies investigating plasma processes at collisionless shocks and their surrounding region.
