Abstract: | Using 15 years of high-resolution solar film obtained at Big Bear Solar Observatory we studied flare-associated filament eruptions. In addition to the classical type eruption consisting of expansion and breakup, we find evidence of another type where a layer is shed from the filament and erupts while the inversion line filament below (or, what is left of it) remains in place. Both types of eruptions are presented in the paper. It is hoped that the new evidence will shed new light on the understanding of the role of filaments in flares. |
