TY - JOUR ID - 45501 AU - Cremaschini, Claudio - Stuchlík, Zdeněk PY - 2013 TI - Magnetic loop generation by collisionless gravitationally bound plasmas in axisymmetric tori JF - PHYSICAL REVIEW E VL - 87 IS - 4 SN - 15393755 KW - 2-Temperature accretion flows KW - Black-Hole KW - Epicyclic frequencies UR - https://journals.aps.org/pre/abstract/10.1103/PhysRevE.87.043113 N2 - Current-carrying string loops are adopted in astrophysics to model the dynamics of isolated flux tubes of magnetized plasma expected to arise in the gravitational field of compact objects, such as black holes. Recent studies suggest that they could provide a framework for the acceleration and collimation of jets of plasma observed in these systems. However, the problem remains of the search of physical mechanisms which can consistently explain the occurrence of such plasma toroidal structures characterized by nonvanishing charge currents and are able to self-generate magnetic loops. In this paper, the problem is addressed in the context of Vlasov-Maxwell theory for nonrelativistic collisionless plasmas subject to both gravitational and electromagneticfields. A kinetic treatment of quasistationary axisymmetric configurations of charged particles exhibiting epicyclic motion is obtained. Explicit solutions for the species equilibrium phase-space distribution function are provided. These ER -
