Interstellar Medium Traces in the Time-Varying Heliosphere

Session ID#: 157057

Session Description:
The local interstellar medium in the solar neighborhood contains plasma, magnetic fields, neutral atoms, and cosmic rays, which influence the heliosphere through interconnected time-dependent and multi-scale processes. The plasma and magnetic field determine the heliospheric boundary where neutral atoms and cosmic rays are filtered. The neutral atoms penetrate the heliosphere, where they are ionized, becoming pickup ions, which are subsequently energized and neutralized, creating energetic neutral atoms. These different components are observed through a combination of in situ sampling and remote imaging by, e.g., Voyager, New Horizons, IBEX, Cassini, and the upcoming IMAP mission. Physical interpretation of these observations requires theories and models on scales from interplanetary shocks to the global heliosphere. In this session, we invite presentations on observations, theory, and modeling concerning plasma, magnetic fields, neutral atoms, pickup ions, and cosmic rays in the time-varying heliosphere and the very local interstellar medium.
