The book starts with the classical examples of hydrodynamical accretion onto relativistic and nonrelativistic objects. The force-free limit of the Grad-Shafranov equation allows us to analyze in detail the physics of the magnetospheres of radio pulsars and black holes, including the Blandford-Znajek process ofenergy extraction from a rotating black hole immersed in an external magneticfield. Finally, on the basis of the full MHD version of the Grad-Shafranov equation the author discusses the problems of jet collimation and particle acceleration in Active Galactic Nuclei, radio pulsars, and Young Stellar Objects. The comparison of the analytical results with numerical simulations demonstrates their good agreement. Assuming that the reader is familiar with the basic physical and mathematical concepts of General Relativity, the author uses the 3+1 split approach which allows the formulation of all results in terms of physically clear language of three dimensional vectors. A didactic approach to understanding accretion flows, winds and jets of Astrophysical Compact Objects. Analytical treatment of the hydrodynamic and magnetohydrodynamic problem revealsphysical concepts and provides better understanding of numerical simulations Contains detailed derivations of equations, a large number of excercises and references INDICE: Preface.- Introduction.- Hydrodynamic limit - classical problems of accretion and ejectionForce-free limit - radio pulsar magnetosphere.- Force-free approximation - black hole magnetosphere.- Full magnetohydrodynamical version - particle acceleration and magnetic collimation.
