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 …

The corona of the Sun is a unique environment in which magnetohydrodynamic (MHD)
waves, one of the fundamental processes of plasma astrophysics, are open to a direct study …

The heating of the solar chromosphere and corona to the observed high temperatures, imply
the presence of ongoing heating that balances the strong radiative and thermal conduction …

Slow magnetoacoustic waves are omnipresent in both natural and laboratory plasma
systems. The wave-induced misbalance between plasma cooling and heating processes …

Solar flare emission is detected in all EM bands and variations in flux density of solar
energetic particles. Often the EM radiation generated in solar and stellar flares shows a …

We analyze the light curve of the M5. 5 dwarf Proxima Centauri obtained by the Transiting
Exoplanet Survey Satellite (TESS) in Sectors 11 and 12. In the≈ 50 day long light curve we …

Quasi-periodic, fast-mode propagating (QFP) wave trains in the corona have been studied
intensively over the last decade, thanks to the full-disk, high spatio-temporal resolution, and …

We present the first results of our ongoing project conducting simultaneous multiwavelength
observations of flares on nearby active M dwarfs. We acquired data of the nearby dM3. 5e …

Here we detail the dynamic evolution of localized reconnection regions about 3D magnetic
null points using numerical simulation. We demonstrate for the first time that reconnection …

In a previous paper, we computed the energy density and the nonlinear energy cascade rate
for transverse kink waves using Elsässer variables. In this paper, we focus on the standing …
