Betelgeuse, the bright, cool red supergiant in Orion, is mov ing supersonically relative to the local interstellar medi um. The star emits a powerful stellar wind that collides with this medium, form ing a cometary structure, a bow shock, pointing in the direct ion of motion. We present the first 3D hydrodynamic simulations of the forma tion and evolution of Betelgeuse’s bow shock. The models inc lude realistic low-temperature cooling and cover a range of plau sible interstellar medium… Expand
