A Plasma Orchestra, or Magnetohydrodynamic Waves in the Solar Corona

Valery M Nakariakov (University of Warwick, United Kingdom)

The corona of the Sun is the outermost part of the solar atmosphere. The corona is a very hot, fully ionised plasma dominated by the magnetic field. The corona is the birthplace of extreme events of space weather, and a natural laboratory for plasma physics. One of the most fascinated discoveries made with recent high-precision spaceborne imaging telescopes operating in the extreme UV band is the ubiquitous dynamics of the corona in a form of various large-scale wave motions. An example of such an instrument is the Extreme UV imager on the recently launched Solar Orbiter spacecraft. Typical oscillation periods are several minutes, typical wavelengths are tens to hundred thousand kilometres, and typical speeds are from several tens to several thousand kilometres per second, which make the solar coronal waves the largest electromagnetic wave motions resolved simultaneously in time and space, detected in the Universe. The observed waves are confidently interpreted in terms of the magnetohydrodynamic theory. Various plasma structures of the corona support different types of wave modes, allowing for the use of the waves for the plasma diagnostics via the method of magnetohydrodynamic seismology.
