The articles in this book deal with energetic hadronprocesses near astrophysical compact objects, includingcompact binary systems and active galactic nuclei. A varietyof observational results suggest that relativistic hadronscan be produced in the vicinity of these objects. Amongthetopics treated in detail are the question whether a largefraction of the energy produced by active galactic nuclei ischanneled into a population of relativistic protons and theproblem of the origin of very high and ultra-high energygamma rays from galactic compact sources.Relativistic hadrons near accreting compact objects: Dynamical and radiative signatures.- Can ultrarelativistic neutrons from the central engine drive the outflow in broad absorption line QSOS?.- Inflation of stars by TeV neutrinos.- Electron-positron pair production in compact sources with energetic protons.- Limit cycles in electromagnetic cascades in compact objects.- Nuclear interactions near accreting black holes.- A new approach to hot accretion disks.- X-ray continuum emission caused by relativistic protons.- Pair cascade model constraints on energetic particle emission from active galactic nuclei.- Jets and hotspots in extragalactic radio sources.- Pion production in strong magnetic fields: A model for gamma-ray emission from accreting X-ray pulsars.- Particle acceleration at shock fronts in AGNs and jets.- Fermi particle acceleration in relativistic shocks: Preliminary nonlinear results.- Cosmic ray transport in AGNs and jets.- Particle Acceleration in Relativistic Shock waves with Oblique Magnetic Fields in the presence of Finite Amplitude Field perturbations.- Collisional Acceleration of Electrons in Central Regions of Active Galactic Nuclei.- Influence of Second-Order Fermi acceleration and Relativistic Shock Waves on Nonthermal Continuum Emission in Hot Spots.- Collimated Relativistic Winds Driven by Electromagnetic Forces.- Ultra-relativistic pulsar wind.- A model of pulsed galS*
