Einführung in die theoretische Astrophysik

What it is about

You will learn fundamental concepts of theoretical astrophysics, from the structure and dynamics of compact objects to stars and up to galaxies and galaxy clusters. In the end you will be able to apply physical principles (gravitation, hydrodynamics, radiative transfer, equations of state), derive simple scaling relations, and describe astrophysical examples such as white dwarfs, stellar evolution, accretion, and shock fronts.

What you will be able to do

• Name observed astrophysical structures and their properties
• Explain reasons for the occurrence of discrete structures on various scales
• Recall fundamental dynamical laws in gravitational systems
• Explain methods of astrophysical mass determination and present arguments for dark matter
• State the fundamentals of stellar properties and stellar evolution up to end states
• Derive scaling relations from differential equations (e.g., stellar structure)
• Describe the fundamental equations of hydrodynamics
• Differentiate between different discontinuities in hydrodynamic flows
• Name the equations of radiative transfer and follow the derivation of the diffusion law
• Name and apply fundamental limits for equations of state of astrophysical plasmas
