Division E Sun and Heliosphere

5 and 8 August 2022

Workshop: Heliophysics in the 21st Century

Scientific Organizing Committee: Cristina H. Mandrini (Co-chair), Toshifumi Shimizu (Co-chair), Timothy S. Bastian, Mingde Ding, Robertus Erdelyi, Ilaria Ermolli, Claire Foullon, Manolis K. Georgoulis, Sarah Gibson, Irina N. Kitiashvili, Heidi H. Korhonen, Alexander Nindos, Durgesh Tripathi

Scientific Rationale

The research covered by Division E includes the study of the Sun, its variability, activity, and dynamics, as well as its impact on the Earth and other bodies within the heliosphere. The proximity of the Sun enables detailed investigation of its structure, the dynamo operating in its interior, and the radiation and solar wind that propagate outward, in the heliosphere. Dynamical phenomena include flares, coronal mass ejections, shock fronts and their propagation, and the acceleration of particles into the interplanetary medium. In addition to the above topics, the Workshop includes a session on recent instrumentation, its status and science.
