2.5 Unified model for flares, microflares, and jets

Figure 11View Image illustrates a unified model that can explain large-scale flares, small-scale flares, flare-like phenomena accompanied by plasmoid ejection on the basis of magnetic reconnection (Shibata, 1999Jump To The Next Citation Point). In the case of large-scale flares, a plasmoid is located in a vertical current sheet formed inside a magnetic arcade, while in the case of small-scale flares, a plasmoid sits in a current sheet formed at the interface between emerging and preexisting fields. In both cases, the ejection of a plasmoid from a current sheet triggers fast magnetic reconnection, producing a flare and flare-like phenomenon (Section 4.1.6). Tables 14 summarize the feature of flares and flare-like phenomena (Shimojo et al., 2007).
