Astrophysical fluid dynamics is a modern branch of astronomy involving fluid mechanics which deals with the motion of fluids, like the gases which the stars are made up of or any fluid which is found in outer space. The subject covers the fundamentals of mechanics of fluids using various equations, ranging from continuity equation, Naiver Stokes to Euler's equations of collisional fluids and the like. It is an extensive study of the physical realms of the astral bodies and their movements in space. A thorough understanding of this subject requires detailed knowledge of the equations governing fluid mechanics. Most of the applications of astrophysical fluid dynamics include dynamics of stellar systems, accretion disks, Astrophysical jets,Newtonian fluids, and the fluid dynamics of galaxies.
