Abstract

Extreme-ultraviolet (EUV) waves are one of the large-scale phenomena on the Sun. They are defined as large propagating fronts in the low corona with speeds ranging from a few tens km s−1 to several 1000 km s−1. They are often associated with solar filament eruptions, flares, and/or coronal mass ejections (CMEs). EUV waves exhibit various features, including wave and non-wave components, stationary fronts, reflection, refraction, and mode conversion. Additionally, they can hit the nearby coronal loops and filaments/prominences during their propagation, triggering oscillations. These oscillations in loops and filaments/prominences enable us to diagnose coronal parameters such as the strength of the coronal magnetic field. In this article, we present the different observed features of the EUV waves along with existing models.

Keywords : EUV waves, coronal mass ejections, coronal oscillations
