Virial theorem, gravitational collapse, and formation of stars. Special relativity. Doppler shift. General relativity and black holes. Relative and absolute magnitude of stars. Binary stars. Planck's law of radiation and Wien's displacement law. Stellar spectra. Nuclear processes in the core of stars. White dwarfs and neutron stars. Cosmology and the Big Bang.
The student will acquire basic knowledge of the solar system and plenatary motion. He/she will get an overview of the formation of stars, the nuclear processes in the core of stars, and their death. Likewise, the student will ackquire an overview of special relativity, general relativity, cosmology, and the Big Bang.
Learning methods and activities
Lectures and problem sessions. Mandatory assignments.
Further on evaluation
The final grade is based on portfolio assessment. The portfolio includes written exam (80 %) and semester assignment (20 %). The evaluation of the different parts is given in %-points, while the entire portfolio is given a letter grade. For a re-take of an examination, all assessments in the portfolio must be re-taken.
The re-sit examination may be changed from written to oral.
Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
