GASEOUS NEBULAE AND GALAXIES: COMPREHENSIVE REPORT.

The report is divided into four parts. In Part I the following subjects are considered the chemical composition of gaseous nebulae and dark clouds in interstellar space dusty clouds and their absorption ability the dynamical physical properties and processes in nebulae, as investigated by spectroscopic and photometric methods distances to the gaseous nebulae gaseous nebulae of the type known cometary nebulae and the artificial sodium cloud. Part II is concerned with studies of various kinds of hot stars. The areas covered include configuration equilibrium studies of stellar atmospheres physical properties of stars, including spectral analysis and polarization novae and the causes of their formation and young supergiant stars and the physical processes within these stars. Part III is devoted to galaxies. Interstellar matter, including the gas motion in the Galaxy and the magnetic field and the structure and dynamics of galaxies and the Metagalaxy clusters are considered. Part IV contains reviews of Soviet works on gaseous nebulae, hot stars, and galaxies. The books reviewed are used as textbooks for advanced students and specialists.
