Slices of the astrosphere model. (a) Distribution of neutral hydrogen number density. (b) Distribution of the neutral hydrogen temperature. (c) Distribution of the neutral hydrogen speed along the line of sight. (d) Distribution of the neutral hydrogen speed along the downwind direction. The 3D astrosphere model is sliced at the X–Z plane, where X is the downwind direction, and Z is aligned with the star’s rotational axis. The interstellar flow comes from the left, and the white symbol represents the inner region below the lower boundary at 30 au.
