Division E: Sun and Heliosphere

9 and 12 August 2024

Workshop: Multi-wavelength Heliophysics from Space and the Ground

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. Earth’s proximity to the Sun enables detailed investigations of its structure, the physical processes operating in its interior and atmosphere, as well as the radiation and the momentum and energy that propagate outward, into the heliosphere. Dynamical phenomena include waves, flares, coronal mass ejections, shock fronts, transient events propagation, and the acceleration of particles in the interplanetary medium.
Our Division E meeting finds solar and heliophysics research in a very advantageous position to address key questions on the above topics. The study of the Sun and its region of influence, the heliosphere, benefits from an unprecedented number of space missions and cutting-edge ground-based observatories providing multi-wavelength and multi-point measurements that span from the photosphere, chromosphere, and corona to the heliospheric in situ plasma, particles, and magnetic field observed from several vantage points at various heliocentric distances.
