The phenomenon of quasi-periodic pulsations (QPPs) in solar and stellar flares has been
known for over 50 years and significant progress has been made in this research area. It has …

Waves and oscillations have been observed in the Sun's atmosphere for over half a century.
While such phenomena have readily been observed across the entire electromagnetic …

Magnetic reconnection, topological changes in magnetic fields, is a fundamental process in
magnetized plasmas. It is associated with energy release in regions of magnetic field …

Context. We investigate the decayless regime of coronal kink oscillations recently
discovered in the Solar Dynamics Observatory (SDO)/AIA data. In contrast to decaying kink …

Magnetohydrodynamic (MHD) oscillatory processes in different plasma systems, such as the
corona of the Sun and the Earth's magnetosphere, show interesting similarities and …

Prominences are intriguing, but poorly understood, magnetic structures of the solar corona.
The dynamics of solar prominences has been the subject of a large number of studies, and …

Modern observatories have revealed the ubiquitous presence of magnetohydrodynamic
waves in the solar corona. The propagating waves (in contrast to the standing waves) are …

Aims. We investigate kink oscillations of loops observed in an active region with the
Atmospheric Imaging Assembly (AIA) instrument on board the Solar Dynamics Observatory …

Turbulent magnetic reconnection is believed to occur in astrophysical plasmas, and it has
been suggested to be a trigger of solar flares. It often occurs in long stretched and …

Magnetic field lines in astrophysical plasmas are expected to be frozen-in at scales larger
than the ion gyroradius. The rapid reconnection of magnetic-flux structures with dimensions …
