Content
Recommended prerequisites:

Students will benefit from being acquainted with basic concepts in Calculus, Mechanics, Electrodynamics, Thermodynamics and Statistical Physics. Knowledge about fluid dynamics is welcome but not essential. Students who would like to take the course but could benefit from brushing up their knowledge in these and related subjects are encouraged to contact M. Pessah in advance in order to discuss useful reading material toward this end.

Academic qualifications equivalent to a BSc degree is recommended.

Aim and content
This fundamental course provides an overview of some of the most important astrophysical processes that shape the evolution, and observational properties, of astrophysical systems, from planets to stars, and from supermassive black holes to entire galaxies. The course is strongly recommended for all students starting at the M.Sc. and Ph.D. levels in preparation for their further study and research in any area of astrophysics, including planetary sciences and cosmology. We will cover the basic equations, learn how to solve them, and understand their implications. This course will provide students with a wide range of interests in observational, theoretical, or computational astrophysics with a valuable toolkit to become more competent researchers.

The aim of this course is to bring together several key concepts in physics and build upon them in order to understand some of the most important processes in astrophysics. This is crucial in order to understand the formation and evolution of a wide range of astrophysical systems. This is a demanding task that is possible to accomplish by attending the lectures and investing the time in doing the weekly homework assignments. This course has been designed in such a way that lectures and weekly assignments come together to achieve the goals sets forth.

Skills
When the course is finished, it is expected that the student is able to:

  • Identify the physical processes involved in a given astrophysical setting
  • Carry out order of magnitude calculations to support physical intuition
  • Solve basic problems involving radiative transfer, wave propagation, instabilities, and shocks in hydrodynamics and magnetohydrodynamics.

Knowledge

When the course is finished, it is expected that the student is able to:

  • Explain the basic astrophysical processes covered by the course content
  • Explain how these processes act together to dictate the dynamics of astrophysical flows such as self-gravitating fluids, disk, winds, and jets.
       

Competences
This course will endow the students with a powerful set of tools that will allow them to work more confidently on a wide variety of subjects in astrophysics. The competences acquired in this course are a valuable complement to those obtained in observational and phenomenological astrophysics courses. These competences are an indispensable asset for students wishing to pursue studies in any branch of astrophysics. This course provides the students with the background knowledge to pursue research in this field and is an excellent preparation for a MSc project.
