The book is comprised of 10 chapters that present the general principles on which it is based and how the modern conceptions of motions in stellar systems can be derived. The text first discusses the fundamentals concepts of stellar statistics, and then proceeds to detailing the kinematics of stellar systems. The next chapter covers the elementary theory of galactic rotation. Next, the book tackles the irregular forces in stellar systems. Chapter V talks about the statistical stellar dynamics neglecting encounters, while Chapter VI deals with the regular orbit of the stars. In the eighth chapter, the text tackles the problem of local dynamics. The remaining chapters deal with the dynamics of centroids, spherical stellar systems, and rotating stellar systems. The book will be of great interest to researchers and practitioners of disciplines that deal with celestial bodies, such as astronomy and astrophysics.
