Session Proposal: The Ice Giants: Investigating the Planetary Systems of Uranus and Neptune (AGU25)

P040
The Ice Giants: Investigating the Planetary Systems of Uranus and Neptune

Session ID#: 247438

Session Description:
The Uranus and Neptune systems are high-priority targets for future space missions that present exciting opportunities for new discoveries. We solicit interdisciplinary topics covering all aspects of ice giant systems, including their formation, evolution, planetary/satellite interior structures, subsurface oceans, surface geology (including possible cryovolcanoes on Triton), atmospheres, aeronomy, aurorae, ionospheres, rings, magnetospheres, and solar wind interactions. We welcome presentations that advance our understanding of ice giant systems from a range of perspectives including observations, modeling, theory, and laboratory work. We also encourage comparative studies between the Uranus/Neptune systems and other planetary bodies within our solar system and beyond.
