Top left: proton density distribution in the ecliptic plane across the whole simulated domain computed with a stellar XUV flux at 1 AU of 6 erg cm⁻² s⁻¹, a stellar mass-loss rate of 10¹¹ g s⁻¹ (i.e. weak SW), and SW terminal velocity of 400 km s⁻¹ (i.e. velocity of 250 km s⁻¹ and temperature of 0.65 MK at the planetary orbit), leading to a SW density at the planetary orbit of 3 × 10² cm⁻³. The axes arescaled in units of planetary radii and the planet sits at the center of the coordinate reference frame, while the star lies at X = 762. Top right: same as top-left, but for a stellar mass-loss rate of 2 × 10¹² g s⁻¹ (i.e. moderate SW), leading to a SW density at the planetary orbit of 6 × 10³ cm⁻³. Bottom left: same as top-right, but for the density distribution of ENAs and closing-up to the position of the planet. Bottom right: same as bottom-left, but for the electron temperature in the X− Z plane. In all panels, the lines with arrows indicate streamlines of the corresponding fluids.
