Аннотация:The neutral gas component of the local interstellar cloud (LIC) flows through the inner heliosphere due to the relative motion of the Sun and the surrounding medium. Interstellar ions are diverted around the heliosphere, which leads to filtration of many species, in particular H and O. A recent coordinated analysis hosted by the International Space Science Institute (ISSI) has produced consolidated physical He parameters from in-situ observations of the neutral He flow. Starting with the assumption that He represents kinetic LIC parameters for all species, a similar effort is underway for interstellar H, which is substantially filtered. Using pick-up ion, solar wind slowdown, and UV scattering observations at various solar distances, and a full chain of modeling from the pristine LIC to the inner heliosphere, the filtering of H and its density in the LIC, as well as ionization fractions and the radiation environment in the LIC are inferred.
