Syllabus
  • Electromagnetic spectrum. Nature and properties of the electromagnetic radiation, its classification according to the wavelengths. Transmisivity of the earth atmosphere for the electromagnetic radiation. The role of the electromagnetic radiation in astrophysics. Radioastronomy. Mechanisms producing the radio emission. Continuum radio emission, radio line emissions, the thermal blackbody radiation, thermal emission from ionized hydrogen, synchrotron radiation, other types of mechanisms producing a non-thermal emission: Cerenkov radiation, plasma oscillations. Radio emission from astrophysical objects. Radio emission from the Sun. Radio emission from the Moon and the planets. Radio emission from other bodies in the solar system. Radio emission from the Galaxy, emission from the galactic radio sources, emission of the neutral hydrogen at 21 cm. Extragalactic radio sources, radio galaxies, quasars. The 2.7 K blackbody cosmic radiation. Radio telescopes. Radio interferometers. Infrared radiation. Mechanisms and the nature of the continuous and the line infrared emission. Radiation of melecular structures: rotational, vibrational and electronic rotation-vibration molecular spectra. Stimulated emission - principle of maser. Astrophysical sources of the infrared radiation. Emission from protostars. Role of the infrared radiation for the investigation of the interstellar matter. The radiation in the near and the far ultraviolet. History of the pre-IUE projects, the main results: a revision of the temperature scale for hot stars, winds from early supergiants, determination of the UV characteristics of interstellar scattering, measurements of interstellar molecular hydrogen. Investigation of the nearest cosmic space using the IUE satellite. Planetary atmospheres, satellites of the planets, comets. IUE investigates the stars. Spectral classification, star wind, special types of stars: Wolf-Rayet stars, symbiotic stars, Be-stars, variable stars. Latest evolution stages of stars: white dwarfs, hot subdwarfs, nuclei of planetary nebulae. Galactic novae. Accretion onto compact stars. Interacting binaries. Interstellar medium in galaxies. Diffuse and dark interstellar clouds, interstellar dust and extinction, absorption lines from highly ionized atoms, supernovae and their remnants, HII regions, planetary nebulae. Active galactic nuclei, quasars, blasars, quasar absorption lines and galaxy halos. X-radiation, its sources and the observational results. X-ray bursts. Gamma radiation. Gamma-bursters and the theory. Neutrino astronomy. Neutrino processes and their role in the evolution of stars.
