Session Proposal: Across the Heliospheric Boundaries and Regions: In-situ Observations and Modeling as Tools for Probing the Outer Heliosphere (AGU25)

SH001
Across the Heliospheric Boundaries and Regions: In-situ Observations and Modeling as Tools for Probing the Outer Heliosphere

Session ID#: 249398

Session Description:
The outer heliosphere, extending from the ionization cavity to the very local interstellar medium (VLISM), is a dynamic region where the solar wind is influenced by its interaction with interstellar material. Voyager 1 and 2 are the only missions to provide in-situ observations of the termination shock, heliosheath, heliopause, and VLISM. Yet many fundamental questions of these regions remain unanswered. New Horizons is currently approaching the termination shock and plans to deliver new observations that advance our understanding of termination shock physics and heliosheath dynamics. Numerical and analytical modeling efforts, such as those from the SHIELD DRIVE Science Center and ISSI teams, provide critical insights into the observed physical processes. We solicit presentations that explore the outer heliosphere and VLISM through data analysis, modeling approaches, and predictions for upcoming observations. We encourage topics concerning plasma, magnetic fields, pickup ions, dust, and cosmic rays in the outer heliosphere.
