Spring 2016

Much of the observable astrophysical phenomena in the universe is composed of partially or fully ionized gasses and for many purposes, as a first approximaton,this plasma can be treated as a fluid. The course will introduce to the principles of fluid dynamics (hydrodynamics) and their fundamental role in astrophysical contexts. The next approximation beyond hydrodynamics is magnetohydrodynamics, which we may introduce toward the end of the course, time-permitting.
