Last update: T_AUUK (25.05.2006)
Basic information on different topics of astrophysics - solar system physics, internal constitution and evolution of stars and on galaxies and on structure and evolution of the Universe. Recent "hot" and open problems in investigation of the Universe will be included, together with some excercises in practical astronomy. No previous knowledge of astrophysics is assumed. The course is convenient for BSc students and for those MSc students who have major fields other than astrophysics but would like to get some fundamentals of it.
