Magnetohydrodynamic models of astrophysical jets

Magnetohydrodynamic Jets Andwinds

The theory of magnetically accelerated outtows and jets from accretion disks is reviewed at an introductory level, with special attention to problem areas like the launching conditions of the ow at the disk surface, stability of the magnetic eld, and collimation mechanisms. This text will appear in R. 1.1 Introduction: the case for magnetic acceleration Narrow, high speed outtows (jets) and les...

Miniconference on astrophysical jets

This miniconference brought together observers of astrophysical jets, analytic and numerical modelers of both astrophysical jets and spheromaks, and laboratory experimentalists. The purpose of the miniconference was to encourage interaction between these diverse groups and also expose the plasma physics community to the interesting plasma issues associated with astrophysical jets. The miniconfe...

A class of exact MHD models for astrophysical jets

This paper examines a new class of exact and self-consistent MHD solutions which describe steady and axisymmetric hydromagnetic outflows from the atmosphere of a magnetized and rotating central object with possibly an orbiting accretion disk. The plasma is driven against gravity by a thermal pressure gradient, as well as by magnetic rotator and radiative forces. At the Alfvénic and fast critica...

Intermittency of Magnetohydrodynamic Turbulence: Astrophysical Perspective

Intermittency is an essential property of astrophysical fluids, which demonstrate an extended inertial range. As intermittency violates self-similarity of motions, it gets impossible to naively extrapolate the properties of fluid obtained computationally with relatively low resolution to the actual astrophysical situations. In terms of Astrophysics, intermittency affects turbulent heating, mome...
