Computational Astrophysics

[Poster] (This course was given in winter semester 2007/2008, winter semester 2008/2009, winter semester 2009/2010 and winter semester 2010/2011 at Technische Universität München, the last two times together with Ewald Müller. In the winter semesters 2011/2012, 2012/2013 and 2013/2014 it was taught at Universität Würzburg together with Christian Klingenberg. Now it is offered again:)

Summer semester 2015 at Universität Heidelberg.
Mondays 2\–4pm(lecture) 4pm (tutorial) Philosophenweg 13, kleiner Hörsaal

Course starts on Monday, April 13, 2015.

Slides shown in the course are available (password is required to prevent automated searches and will be provided in class).

Syllabus

The subject of astrophysics are complex objects and phenomena. Seeking for a theoretical understanding, a realistic description is required. To this end, computers have become a major tool of research and with ever more powerful computational resources and modern numerical techniques, a detailed modeling of astrophysical objects has become feasible. Based on general strategies to numerically model astrophysical phenomena, the course aims at describing some recent developments in computational astrophysics. The folowing topics will be covered:
  • astrophysical concepts
  • numerical concepts
  • modeling gravity
  • computational fluid dynamics
  • modeling nuclear reactions
  • magnetohydrodynamics
  • turbulence
  • modeling radiative transfer

Introduction to Computational Astrophysics

[Poster] XXIV Heidelberg Physics Graduate Days
of the Heidelberg Graduate School of Fundamental Physics and the Department of Physics and Astronomy
University of Heidelberg
April 6 – 9, 2010

Slides shown in the course and example programs are available (password is required to prevent automated searches and will be provided to participants at the course.

Syllabus

The subject of astrophysics are complex objects and phenomena. Seeking for a theoretical understanding, a realistic description is required. Therefore, computers have become a major tool of research and with ever more powerful computational resources and modern numerical techniques, a detailed modeling of astrophysical objects has become feasible. I will give an introduction to basic concepts of numerical modeling in astrophysics which can serve as building blocks for developing research-oriented implementations.
