Solar and stellar coronal loops

Advances in Space Research, 1991
Abstract X-ray and EUV pictures from space experiments (e.g. SKYLAB ) have revealed that the corona of the Sun consists of a variety of discrete structures - involving a range of timescales - which appear to outline the magnetic field lines emerging from the convection zone below the photosphere.

Pressure structure of solar coronal loops, III

Solar Physics, 1992
The theory of ideal magnetohydrodynamic turbulence in cylindrical geometry is used to study the steady-state structure of a coronal loop. The pressure profile is derived from MHD equations by representing the velocity and magnetic fields as the superposition of Chandrasekhar-Kendall functions.

Modelling of a solar coronal loop

Journal of Plasma Physics, 1996
Montgomery and co-workers have developed a framework to describe the steady state of a turbulent magnetofluid, without the usual recourse to linearization. Thus the magnetic and velocity fields emerge in their fully nonlinear form as a consequence of the selective decays of the invariants of the system.

Nonlinear wave heating of solar coronal loops.

Astronomy and Astrophysics, 1997
The heating of magnetically closed structures (loops) in the solar corona by the resonant absorption of incident waves is studied by means of numerical simulations in the framework of nonlinear resistive magnetohydrodynamics (MHD). It is shown that the dynamics in the resonant layer is indeed very nonlinear for typical coronal parameters. The effect of

Temporal evolution of resonant absorption in solar coronal loops

Computer Physics Communications, 1990
Abstract A numerical code is presented for the computation of the temporal evolution of an externally driven cylindrical plasma column in the framework of linearized compressible and resistive magnetohydrodynamics. The partial differential equations are solved with a semi-discretization method using cubic and quadratic finite elements for the spatial

Explosive Instability in Solar Coronal Loops

1991
The presence of shear flows along the stretched magnetic field structures such as solar coronal loops change their dynamics essentially, and, particularly, can lead to the explosive instabilty which results in the fast and efficient energy release.

Theory of Transverse Oscillations of Solar Coronal Loops

AIP Conference Proceedings, 2009
We consider transverse oscillations of coronal loops first observed by TRACE on 14 July 1998. We mainly concentrate on theory of these oscillations, although relevant observational results are also discussed. The transverse coronal loop oscillations were interpreted as standing fast kink waves in magnetic flux tubes.
