The magnetic viscosity tensor is derived for a magnetized relativistic collisionless plasma with temperature gradients. By means of this tensor we deduce the nonlinear equations for drift–Alfvén waves in a relativistic electron-positron low plasma with density and temperature gradients. It is shown that our new equations have solutions in the form of dipolar vortices. The present results should be relevant to a number of astrophysical objects with strong electron-positron pair production, e.g. in pulsars as well as in accretion disks and jets. 相似文献

A set of equations which governs the nonlinear dynamics of drift–Alfvén waves in an inhomogeneous relativistic electron-positron
plasma with a small admixture of heavy ions is derived. It is shown that these equations admit a stationary solution in the
form of a two-scale dipolar vortex. The conditions for the existence of such structures are discussed. It is shown that the
presence of heavy ions in are lativistic electron-positron plasma significantly reinforces the spatial localization of the
solitary waves which results in the appearance of exponentially localized vortex structures. It is also shown that the small
scale micropulse structure of radio pulsar radiation (e.g., in the case of the pulsar PSR 0905+08) can be interpreted as a
signature of the vortex structure in the outer region of the pulsar polar magnetosphere.
