Non-rotating Spherically-symmetric Blackhole Spacetimes

The book is aimed at describing spherically-symmetric non-rotating blackkhole spacetimes surrounded of media; the media considered are the Relativistic dusts the Relativistic plasmas and the Relativistic gaseous materials. The General-Relativistic implementation established after the definition of the positions and of the velocities of the generic observer; the configurations are analytically calculated after the stress-energy tensor. The Relativistic-Astrophysical implementation is provided with after the description of the investigation of the phenomena which characterize the several blackhole environments: for these purposes the Relativistic Jeans gas the adiabatic perturbations of the perfect fluids and the 3-velocities perturbations of the gas are considered. The new behaviors are analytically written of the velocities. Furthermore the paradigms of temperature-descending fluid which characterize some of the events taking place in the corona of the AGN region of the supermassive blackholes are fixed: the new Landau-Lifshitz-Pitaevskii Magneto-Hydrodynamics of the pressure fluid is newly analytically found.
