Tree-based solvers for adaptive mesh refinement code FLASH -- IV: An X-ray radiation scheme to couple discrete and diffuse X-ray emission sources to the thermochemistry of the interstellar medium
Brandt A. L. Gaches, Stefanie Walch, Richard Wünsch +1
X-ray radiation, in particular radiation between 0.1 keV and 10 keV, is evident from both point-like sources, such as compact objects and T-Tauri young stellar objects, and extende…
Evolution of wide O star binaries through their LBV stage. Population synthesis with mass-ejection-driven orbital evolution
Xiao-Tian Xu, Philipp Podsiadlowski, Norbert Langer +6
Context. Long-period Wolf-Rayet (WR) star binaries produced by mass transfer are predicted to be abundant, but are observationally rare. This yields constraints on the evolution of…
Bridging Machine Learning and Cosmological Simulations: Using Neural Operators to emulate Chemical Evolution
Pelle van de Bor, John Brennan, John A. Regan +1
The computational expense of solving non-equilibrium chemistry equations in astrophysical simulations poses a significant challenge, particularly in high-resolution, large-scale co…
Thermal emission from bow shocks. III. Variable diffuse X-ray emission from stellar-wind bow shocks driven by dynamical instabilities
Jonathan Mackey, Arun Mathew, Ahmad A. Ali +5
X-ray emission from wind-driven bow shocks is both difficult to measure and predict, but may give important insights into the energy budget of the hot phase of the ISM by quantifyi…
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 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…
