Astrophysical Gas Dynamics

About this programme

While involving many visually stunning phenomena, gas dynamics is governed by partial differential equations (PDEs) that are among the very first PDEs ever written down. You will gain a clear physical understanding of these equations and learn how they can be applied to explain phenomena such as sound waves, shocks or some cloud patterns. The majority of the course will be based on analytical techniques (but often illustrated by the results of numerical simulations) and will therefore require a good command of standard calculus. Since many phenomena are too complex to be handled analytically, the course also provides a “in a nutshell introduction” to basic numerical techniques for the solution of the gas dynamical equations. The course is given during daytime and is a mandatory course in the Master’s Programme in Astronomy and Astrophysics. It can also be taken as a freestanding course if you fulfil the entry requirements. The course is taught in English. Assessment will be carried out through exercises during the course and a final written exam. "The Principles of Astrophysical Fluid Dynamics" by Clark and Craswell (ISBN: 9780521853316). To follow your passion. To be close to international career opportunities. To explore city and countryside. In Stockholm you can really get the best of both worlds.
