Coronal loop oscillations and flare shock waves
A statistical analysis of coronal loop oscillations observed by TRACE shows that 12 of 28 cases were associated with metric type II bursts. The timing is consistent with the idea that the loop oscillations in many cases result from the passage of a large-scale wave disturbance originating in a flare in the nearby active region. The GOES classifications for these flares range from C4.2 to X20. T...
متن کاملASTRONOMY AND ASTROPHYSICS Heating of coronal holes by phase mixing
A two-dimensional, analytical, self-similar solution to the Alfvén wave phase mixing equations is presented for a coronal hole model. The solution shows clearly that the damping of the waves with height follows the scaling predicted by Heyvaerts & Priest 1983 at low heights, before switching to an algebraic decay at large heights. The ohmic dissipation is calculated and it is shown that the max...
متن کاملHigh-frequency torsional Alfvén waves as an energy source for coronal heating
The existence of the Sun's hot atmosphere and the solar wind acceleration continues to be an outstanding problem in solar-astrophysics. Although magnetohydrodynamic (MHD) modes and dissipation of magnetic energy contribute to heating and the mass cycle of the solar atmosphere, yet direct evidence of such processes often generates debate. Ground-based 1-m Swedish Solar Telescope (SST)/CRISP, Hα ...
متن کاملEnhanced phase mixing of Alfvén waves propagating in stratified and divergent coronal structures
Aims. To explore the solar coronal heating enigma by an analytical and numerical study of the enhanced phase mixing of harmonic Alfvén waves propagating in gravitationally stratified coronal structures of varying magnetic field divergence. Methods. Corrected analytical solutions are derived to model the dissipation of Alfvén waves propagating in divergent and stratified coronal structures. Thes...
متن کاملHeating of ions by Alfvén waves via nonresonant interactions.
Finite-amplitude intrinsic Alfvén waves exist pervasively in astrophysical and solar-terrestrial environment. It is generally believed that linear wave-particle resonant interaction between thermal protons and Alfvén waves is ineffective when the proton beta is low. However, this Letter demonstrates that the ions can be heated by Alfvén waves via nonresonant nonlinear interaction. Contrary to t...
