Commission E4 Impact of Magnetic Activity on Solar and Stellar Environments

Scientific Objectives

The inter-division IAU Commission E4 – Impact of Magnetic Activity on Solar and Stellar Environments – was established in the year 2021 and had its origins in the inter-division Working Group of the same name which was initiated in the IAU General Assembly in Beijing, 2012. The goals of this Commission are to facilitate the understanding of the impact of solar and stellar magnetic activity on their space environments and the (exo)planets they host. With recent advances in observational studies of Sun, heliosphere, stellar magnetic activity and exoplanets and theoretical and modelling initiatives in the emerging sciences of star planet interactions, we expect rapid advances in this interdisciplinary science.
