چکیده

We present Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) observation of three types fast-mode, propagating, magnetosonic waves in a GOES C3.0 flare on 23 April 2013, which was accompanied by prominence eruption and broad coronal mass ejection (CME). During the fast-rising phase prominence, large-scale, dome-shaped, extreme-ultraviolet (EUV) wave firstly formed ahead CME bubble propagated at speed about 430 km s−1 CME’s lateral direction. One can identify separation process EUV from bubble. The reflection effect on-disk counterpart this also observed when it interacted with remote active region. Six minutes after first appearance wave, quasi-periodic train period 120 seconds, emanated epicenter outward an average up to 1100 s−1, appeared inside In addition, another narrow, train, epicenter, 475 110 along closed-loop system connecting two adjacent regions. propose that all are fast-mode waves, dome-shaped driven expansion bubble, while within narrow were excited intermittent energy-releasing flare. Coronal seismology application energy carried estimated based measured parameters.

Fast Magnetosonic Waves Driven by Gravitational Waves

The propagation of a gravitational wave (GW) through a magnetized plasma is considered. In particular, we study the excitation of fast magnetosonic waves (MSW) by a gravitational wave, using the linearized general-relativistic hydromagnetic equations. We derive the dispersion relation for the plasma, treating the gravitational wave as a perturbation in a Minkowski background space-time. We show...

Fast magnetosonic waves in pulsar winds

Fast magnetosonic waves in a magnetically-dominated plasma are investigated. In the pulsar wind, these waves may transport a significant fraction of the energy flux. It is shown that the nonlinear steepening and subsequent formation of multiple shocks is a viable mechanism for the wave dissipation in the pulsar wind. The wave dissipation both in the free pulsar wind and beyond the wind terminat...

Cosmic ray acceleration by fast magnetosonic waves

Recently, Schlickeiser and Miller have calculated anew the acceleration rate of cosmic rays by fast magnetosonic plasma waves in a small-beta plasma, using a linear dispersion relation. They found that the transit-time damping of fast mode waves provides the dominant contribution to the stochastic acceleration rate of cosmic ray particles, both, in pure fast mode wave turbulence as well as in a...

Swing Absorption ’ of fast magnetosonic waves in inhomogeneous media

The recently suggested swing interaction between fast magnetosonic and Alfvén waves (Zaqarashvili & Roberts 2002a) is generalized to inhomogeneous media. We show that the fast magnetosonic waves propagating across an applied non-uniform magnetic field can parametrically amplify the Alfvén waves propagating along the field through the periodical variation of the Alfvén speed. The resonant Alfvén...

Fast magnetosonic waves launched by transient, current sheet reconnection

A model is investigated describing the resistive dissipation of a finite, two-dimensional current sheet subject to suddenly enhanced resistivity. The resistivity rapidly diffuses the current to a distance where it couples to fast magnetosonic modes. The current then propagates away as a sheath moving at the local Alfvén speed. A current density peak remains at the X-point producing a steady ele...
