A new sight at compressive waves in the solar corona

Abstract
Introduction. To date, the nature of the compression waves observed in the solar corona in the extreme ultraviolet range has not been clarified. The established approach to the problem of heating the coronal plasma is based on the concept of magnetoacoustic waves generated in the lower layers of the atmosphere. However, numerous observations and analyses of the spectra of compression waves show features that differ significantly from those of conventional waves.
Results and discussions. We have proposed a new model that considers a sequence of individual localized disturbances instead of a regular wave.
Conclusion The practical significance of the article is based on the properties of acoustic waves, the dynamics of which are significantly influenced by the thermal conductivity and radiation of the plasma, which has shown that the observed features can be explained on a completely different basis. We believe that what is actually observed are chains of localized disturbances generated in the lower atmosphere.
