Skymaps of observables of three-dimensional MHD astrosphere models — •Lennart Robin Baalmann — Ruhr-Universität Bochum

Sky maps of three-dimensional MHD single-fluid models of astrospheres are created by projecting the modeled cells on the surface of a sphere. By choosing different physical parameters to be integrated, sky maps of different observables can be created, e.g. the Hα flux, the bremsstrahlung flux, the cyclotron flux, the Faraday rotation measure or the column density. The method is applied to the astrospheres of different stars, including λ Cephei and the Sun (heliosphere). Compared to current observational limits, only the fluxes of the λ Cephei astrosphere may be observed.
