Prerequisites
The graduation of the courses "An introduction to stellar physics", "An introduction into physics of stellar systems" and "The physics of stellar atmospheres" is strongly recommended.
Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives
The course is an introduction to the study of early type stars and binaries with early type components. The topic corresponds to the research field of a group of members of the Department of Theoretical Physics and Astrophysics. The students obtain information that allows them to do research work in the field of early type stars.
Syllabus
  • Definition of hot stars
  • Main characteristics - mass, temperature, luminosity, population membership, distribution in Galaxy

  • Inner structure
  • Evolutionary status (repetition of stellar structure and evolution).
  • Binaries and multiple systems with hot components
  • Role of hot stars in the Galaxy evolution.
  • Spectroscopic and photometric analysis of hot stars.
  • Variability of hot stars - pulsations: delta Sct, beta Cep, ZZ Cet
  • Early type chemically peculiar stars
  • Be stars
