Stellar flare research is an exciting and rapidly developing field of astrophysics. The Sun is an invaluable proving ground to test predictions of flare theories and to develop analytical techniques for future stellar applications, because the lack of spatial resolution for stellar flares pushes us to extrapolate models of solar flares to the stellar situation. Stellar flares can sometimes be several orders of magnitude more energetic than their solar counterparts, which may suggest that new phenomena are taking place which are not observed on the Sun. Because of widely different energy ranges and atmospheric properties, the investigation of stellar flares is seen as a potential breakthrough in our understanding of flares as a whole. Because flarelike physical processes occur in diverse astrophysically interesting regimes, the field of solar and stellar flares, and therefore, their modelling can serve as an astrophysical touchstone.
