Comparison of astrospheres around cool and hot stars

[摘要] Simulations of astrospheres around hot and cool stars have recently move into the focus of scientific research. We describe here the differences between the astrospheres around hot and cool stars. While those around the former are huge (on pc scales) because of their high stellar wind momentum flow, those around cool stars are on a AU scale and the heliosphere can be used as a standard. Here, we will compare the differences and commonalities between such astrospheres.
