    The Role of Electrons and Helium Atoms in Global Modeling of the Heliosphere by F. Fraternale, N. V. Pogorelov, R. K. Bera

    Published 2023-01-01
    “…We present a new three-dimensional, MHD-plasma/kinetic-neutrals model of the solar wind (SW) interaction with the local interstellar medium (LISM), which self-consistently includes neutral hydrogen and helium atoms. This new model also treats electrons as a separate fluid and includes the effect of Coulomb collisions. …”
