Wave and oscillatory activity of the solar corona is confidently observed with modern
imaging and spectral instruments in the visible light, EUV, X-ray and radio bands, 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 …

The flow of energy through the solar atmosphere and the heating of the Sun's outer regions
are still not understood. Here, we report the detection of oscillatory phenomena associated …

Alfvén waves are considered to be viable transporters of the non-thermal energy required to
heat the Sun's quiescent atmosphere. An abundance of recent observations, from state-of …

The physical mechanisms behind accelerating solar and stellar winds are a long-standing
astrophysical mystery, although recent breakthroughs have come from models invoking the …

A microwave burst with quasi-periodic pulsations was studied with high spatial resolution
using observations with the Nobeyama Radioheliograph (NoRH). We found that the time …

Recent numerical studies revealed that transverse motions of coronal loops can induce the
Kelvin–Helmholtz instability (KHI). This process could be important in coronal heating …

Observations show various jets in the solar atmosphere with significant rotational motions,
which may undergo instabilities leading to heat ambient plasma. We study the Kelvin …

In the context of coronal heating, among the zoo of magnetohydrodynamic (MHD) waves
that exist in the solar atmosphere, Alfvén waves receive special attention. Indeed, these …

Aims. We analysed the consecutive height series of Hα spectra in solar limb spicules taken
on the 53 cm coronagraph of Abastumani Astrophysical Observatory at the heights of 3800 …
