Knowledge of the Czech language is essential for participation in the course.
The student's active participation in seminars, the ability to solve homework independently and work with literature are assumed. - Course Enrolment Limitations
- The course is also offered to the students of the fields other than those the course is directly associated with.
- fields of study / plans the course is directly associated with
- Astrophysics (programme FU, FYZB)
- Course objectives
- The aim is to acquaint the student with various astrophysical processes in stars, interstellar gas, accretion disks, galaxy nuclei, etc., having their descriptive theoretical background in the framework of electromagnetic radiation, hydromechanics, magneto-hydrodynamics and plasma physics.
- Learning outcomes
- The content of lectures and accompanying exercises are physical processes involving electromagnetic radiation, hydromechanics, magneto-hydrodynamics and plasma physics, which are directly related to astrophysical processes in stars, interstellar gas, accretion disks, galaxy nuclei, etc.
Student will gain knowledge in these areas, including the ability to apply them in various situations. - Syllabus
- Lectures (exercises) will be held in the Czech language with the following structure:
