Stationary state of the unperturbed astrosphere. Top row: contour plots of log (n[cm⁻³]) for the final time steps of the lores (left) and hires (right) grids in the ecliptic plane (distances in pc); the cornered structure reflects the model cells. Centre row: synthetic face-on observations of the respective planes in Hα [erg cm⁻² s⁻¹ sr⁻¹]. Bottom row:synthetic observations in infrared dust emission at 70 μm, [Jy sr⁻¹ ] (angular extent in degrees). At a distance of 617 pc, 1° corresponds to 10.8 pc. The solid angles per pixel are 5.07 × 10⁻⁸ sr (lores) and 1.00 × 10⁻⁸ sr (hires).
