Comparison of the telegraph and hyperdiffusion approximations in cosmic-ray transport
(American Institute of Physics (AIP), 2016)The telegraph equation and its generalizations have been repeatedly considered in the models of diffusive cosmic-ray transport. Yet the telegraph model has well-known limitations, and analytical arguments suggest that a ... -
Current singularities in planar magnetic X points of finite compressibility
(American Institute of Physics, 2005-07-15)The formation of current singularities in nonresistive, line-tied magnetic X points is addressed. It is pointed out that, although gas pressure suppresses the current singularity development when strictly antiparallel, ... -
Effects of non-isotropic scattering, magnetic helicity, and adiabatic focusing on diffusive transport of solar energetic particles
(The American Astronomical Society, 2012)Transport of solar energetic particles in interplanetary space is analyzed. A new systematic derivation of the diffusion approximation is given, which incorporates the effects of non-isotropic scattering, magnetic helicity, ... -
Energy losses by anisotropic viscous dissipation in transient magnetic reconnection
(IOP Publishing Ltd, 2010)Global energy losses associated with transient magnetic reconnection in a viscous resistive plasma are examined. The Braginskii stress tensor is used to model the plasma viscosity for conditions typical of the solar corona. ... -
Estimating the size of the cosmic-ray halo using particle distribution moments
(EDP Sciences, 2009)Context: Particle transport in many astrophysical problems can be described either by the Fokker–Planck equation or by an equivalent system of stochastic differential equations. Aims: It is shown that the latter method can ...
