Explosive Magnetotail Activity: Studies throughout the Solar System during the Spaceflight Era

Session ID#: 78632

Session Description:
Six decades of in situ space exploration have revealed that energy stored in Earth’s magnetotail by Solar Wind-Magnetosphere interactions is regularly released in an explosive manner, involving abrupt dipolarizations of the magnetic field and plasma transport from the magnetotail to the inner magnetosphere at multiple spatial scales. Planetary and solar missions have revealed similar phenomena in magnetotails of other planets and moons and the Sun's corona, even though their plasma sources and global transport processes may be different. AGU's Centennial provides a forum to reflect on progress in understanding the extent to which these processes have similar underlying physics, and their effects throughout the solar system. This session calls for presentations from data analysts, experimentalists, modelers and theorists alike, bridging the space, solar, and planetary communities in the attempt to obtain a comparative and comprehensive view of explosive phenomena in magnetized plasmas of the solar system.
