Astrophysical Fluid Dynamics is the study of how fluids, such as gases and plasmas, behave in the context of astronomical phenomena. This field combines principles from fluid dynamics and astrophysics to understand the movement and interaction of these fluids in environments like stars, galaxies, and interstellar space. Researchers in this area analyze processes like stellar formation, supernova explosions, and galactic winds. By applying mathematical models and simulations, they can predict how these fluids influence the structure and evolution of celestial bodies and the universe as a whole.
