Elementary Properties of a Degenerate Fermi GasWe deal in this section with relatively elementary and well known results of the theory of special relativity. However, most of the corresponding . used either in astrophysics or in statistical physics are rather unusual. Therefore a few words about these notations can be useful even for some advanced readers.

Theory of Spectroscopic and Eclipsing Binaries. Stellar MassesLet us consider a system of two celestial bodies revolving about their center of mass under the influence of their mutual gravitational attraction. Such a system can take various forms: the Sun and one of the planets of the solar system; Earth and Moon; a planet and one of its satellites; a binary star; and a double galaxy.

Galactic X-ray SourcesBy ‘galactic’ X-ray sources we mean below all sources situated either in the galactic disk or in the galactic ‘bulge’, but also those associated with some of the globular clusters surrounding our galaxy, and even those situated in such satellites of our galaxy as the Small and the Large Magellanic clouds.

Elementary Theoretical Cosmology: The Newtonian ApproachCosmology attempts to find the physical and the geometrical properties of the universe, i.e. its form, dimensions, mass, composition, ‘age’, etc., considered . and from an . However, some local properties of the universe are also usually considered in elementary cosmology.

Basic Concepts of Relativistic CosmologyThe Newtonian approach, quite sufficient in a popularized account or in an elementary introduction, still leaves out many important problems and all properties of the universe .
