Wind bubbles within H II regions around slowly moving stars
Jonathan Mackey, Vasilii V. Gvaramadze, Shazrene Mohamed +1
Interstellar bubbles around O stars are driven by a combination of the star's wind and ionizing radiation output. The wind contribution is uncertain because the boundary between th…
The wonderful complexity of the Mira AB system
S. Ramstedt, S. Mohamed, W. H. T. Vlemmings +17
We have mapped the CO(3-2) line emission around the Mira AB system at 0.5 resolution using the Atacama Large Millimeter/submillimeter Array (ALMA). The CO map shows amazing complex…
Interacting supernovae from photoionization-confined shells around red supergiant stars
Jonathan Mackey, Shazrene Mohamed, Vasilii V. Gvaramadze +5
Betelgeuse, a nearby red supergiant, is a runaway star with a powerful stellar wind that drives a bow shock into its surroundings. This picture has been challenged by the discovery…
Effects of stellar evolution and ionizing radiation on the environments of massive stars
Jonathan Mackey, Norbert Langer, Shazrene Mohamed +3
We discuss two important effects for the astrospheres of runaway stars: the propagation of ionizing photons far beyond the astropause, and the rapid evolution of massive stars (and…
The Circumstellar Medium of Massive Stars in Motion
Jonathan Mackey, Norbert Langer, Dominique M. -A. Meyer +4
The circumstellar medium around massive stars is strongly impacted by stellar winds, radiation, and explosions. We use numerical simulations of these interactions to constrain the…
