- The graduation of the courses "An introduction to stellar physics" in and "An introduction into physics of stellar systems" is recommended.
- 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
- Applied Physics (programme PřF, B-AF, specialization Astrophysics)
- Physics (programme PřF, M-FY)
- Upper Secondary School Teacher Training in Physics (programme PřF, M-FY)
- Course objectives
- At the end of this course students of physics/astrophysics become more familiar with the basic of stellar spectroscopy and mainly photometry, photometric investigations of variable stars, basic methods of variable star research and futher with the physics of variable stars, characteristics of different types of variable stars.
- Syllabus
- The basic of stellar photometry. Photometric quantities. Photoelectric and CCD photometry. Atmospheric extinction. Photometric observations and basic processing of them. Transformation into standard/international system. Photometric systems used in stellar astrophysics. Coulors indices, colour diagrams and their interpretations. Interstellar extintion. Absolute spectrophotometry and its usage. H-R diagram and its forms. Methods of variable star research. History of variable star research. Classification. Periodicity of variations, search and determination of light ephemeris. O-C investigation. Physics of variable stars. Mechanism of variability: geometric and intrinsic variable stars. Stellar activity and its manifestations. Pulsating variable stars. Astroseismology. Supernovas, gamma ray burst. Characteristics of individual types of variable stars. Global photometric characteristics, light curves and their explanations. Spectroskopy of variable stars, kinematic features, occurence in our Galaxy. Eruptive, rotating and cataclysmic variable stars, eclipsing binaries.

- Assessment methods
- 2 hours lectures, consultations are also possible. Exam: student draws lots 2 questions, he can prepare to answer them for 60 minutes; he can use arbitrary aids including (text)books, notes...; the exam itself is oral and takes about 30 minutes with the aim to find how a student comprehends the content of a course.
- Language of instruction
- Czech
- Further comments (probably available only in Czech)
- The course is taught once in two years.
