physics galaxy book
The book includes a number of new data obtained in recent years, in particular material relating to the recently discovered new structures in spiral galaxies: giant anticyclones, cyclones and slow bars. New methods for the detection of these structures are described. Types of vertical motions of stars and gas in the galaxies, whether due to the presence of spiral armsor hose instability. An important place is given to modern numerical methods of describing the dynamics of galaxies, stellar as well and gas components. andnbsp; Algorithms of numerical models and a number of important results are presented. Other topics discussed in the book include: the role of vertical motions in the disk systems and a new two-dimensional model of the gas disk, the theory of turbulence; a simple self-consistent model of the inhomogeneous differentially rotating hot stellar disk of finite thickness; conditions for stability of stellar disks, taking into account the worse stabilizability of nonaxisymmetric disturbances compared to axisymmetric one; technique of construction of numerical dynamical models of gas and collisionless stellar disks; gravitational-hydrodynamic concept of spiral structures; problems in the dynamics of disks taking into account non-linear factors; a method of reconstruction of the three-dimensional velocity field of gas from the observational data; dynamic role of various components: the bulge, bar, halo, spirals; the dynamics of accretion disks; comprehensive analysis of large-scale processes in the accretion disk of binary stars, etc. andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; andnbsp; About the Author: A.M. Fridman was a Russian physicist specializing in astrophysics, physics of gravitating systems and plasma physics. He discovered new types of instabilities in gravitating media, created the theory of planetary rings and predicted the existence of small Uranus satellites that were later discovered. He also developed hydrodynamic theory of the spiral structure in galaxies. Fridman worked at the lnstitute of Astronomy of the Russian Academy of Sciencesand was professor of Moscow Institute of Physics and Technology and Moscow State University. In plasma physics, A.M. Fridman predicted the existence of the Alfvenandrsquo;s solutionsand worked out the stability theory of thermonuclear plasma at finite high pressure. A.M. Fridman discovered new types of non-Jeans instabilities in gravitating media, some of which develop at timescales less than Jeansandrsquo; timescale, while others exist in systems that are stable according to Jeans.
