The characteristics of different solar system bodies and how they respond to the dynamic heliospheric conditions can be used as an analog for space weather conditions at exoplanets in different stellar systems. With the availability of detailed spacecraft observations in the heliosphere, in combination with advanced modeling techniques, we may now better understand space weather conditions and effects at planets and satellites within our solar system and apply this knowledge towards studies of space weather at exoplanetary bodies. In particular, the heliospheric influences on various bodies can be different for a given solar eruption event, depending on the plasma environment of the planet (e.g., airless or tenuous atmosphere, with or without a magnetosphere).
This session will cover a range of interrelated topics, including the propagation and evolution of ICMEs and SEPs in the heliosphere, the space weather responses by planets, moons, and asteroids, and the expected space weather conditions at exoplanets, particular those within habitable zones of their stellar systems. We welcome both observational and modeling studies on the heliosphere and exoplanetary systems.
