About this Research Topic
Solar coronal waves frequently appear as bright disturbances that propagate globally from the eruption center in the solar atmosphere, just like tsunamis in the ocean on Earth. Coronal waves can be associated with large-scale coronal mass ejections and flares and small-scale jets, and have been interpreted in the model of true magnetohydrodynamic (MHD) waves, pseudo-waves, or hybrid waves. Before the observational discovery of coronal waves, their existence was predicted by the detection of chromospheric Moreton waves in the 1960s. Theoretically, Moreton waves are interpreted as ground tracks of coronal fast-mode MHD wavefronts that sweep over the chromosphere. Large scale coronal waves are also offering a unique opportunity to diagnose the solar corona at a large scale using techniques similar to the seismology of Earth.
The research topic will be dedicated to original results aimed to answer key questions related to the nature, properties and effects of coronal global waves. These questions address:
- What is the reason behind the lack of observations of chromospheric and transition region (TR) counterparts of coronal global waves, why did most coronal waves fail to ignite a detectable chromospheric disturbance?
- how can coronal global waves be used to diagnose the large scale structure of the coronal magnetic field, the plasma parameters and their sources?
- what is the connection between global and local coronal waves, i.e., the connection between global and local coronal seismology
In this Research Topic, we welcome original research and review articles involving observations, simulations, or theoretical investigations of the properties and effects of solar coronal waves and their imprints in the lower atmosphere. The contributions to this research topic will help in better understanding the physical nature and driving mechanisms of solar coronal waves, and their diagnostic possibilities.
