This book describes and reviews observations and investigations of the unique object SS433 obtained after 23 years of studying the massive binary system.The main difference between SS433 and other known X-ray binaries is the action of a constant supercritical regime for the accretion of gas onto the relativistic star (most likely a black hole) which has led to the formation of a supercritical accretion disk and collimated relativistic jets. The properties of jets are to a large extent determined by their interaction with disk wind. The precession of the disk and jets as well as the eclipsing in the binary system make SS433 a unique laboratory for studies of mechanisms for the microquasar phenomenon. The author describes the main ideas and results emerging from studies of the formation of the jets and supercritical accretion disk in SS433.

This book presents and reviews the results of studies on subjects closely related to the problems of abundance anomalies in globular clusters and covers in particular the problem of deep mixing in globular-cluster red giants and describes a diffusion model and a mechanism for extra mixing in red giants. The author traces the development of scenarios to explain the origin of star-to star variations in elemental abundances in globular clusters: primordial nucleosynthesis and mixing and the background to the proposal of a combined scenario and a model for the chemical evolution of globular clusters. This review provides a useful reference text for graduates and researchers in astrophysics.

The optics of small particles are useful in the interpretation of observational phenomena related to extinction, scattering and emission of radiation by dust grains in space. This review presents three components of dust modelling: Optical constants; Light scattering theories and models. The author aims to show how the general laws of the optics of dust particleswork and to highlight the information about cosmic dust. Part II will be dedicated to the consideration of scattered radiation, dust absorption and emission, radiation pressure and dust properties.

Many properties of solids are related to crystal lattice oscillations and this phenomonen is of theoretical significance. This review describes experimental investigations of heat atom vibrations and associated data including specific physical values which have been measured directly and also the methods for X-ray measurements of the mean-square atom displacements.

This volume presents a current review of knowledge on elementary collision processes of highly excited atoms with neutral particles. It provides the basic physical approaches and theoretical techniques for the description of a broad class of observed collision phenomena in gases and low temperature plasmas involving Rydberg atoms. The author considers different mechanisms of inelastic and quasielastic collisions with a change in the principle and orbital quantum numbers, transitions between the fine-structure components, direct and associative ionisation, ion-pair formation and electron-ion recombination processes.
