Can Small-scale Eruptions in the Quiet Sun Propagate into the Higher Solar Corona?

Abstarct Recent research has revealed that small-scale coronal mass ejections (CMEs) in the quiet Sun exhibit similarities in their formation mechanisms and eruption characteristics when compared to large-scale solar eruptions. The occurence of small-scale CMEs increases exponentially as their size decreases. Thus, the role of small-scale CMEs in solar wind formation should not be underestimated. Can small-scale eruptions in the quiet Sun propagate into the higher solar corona? I analyze a typical small-scale eruption in the quiet Sun and reconstruct a flux-rope (FR) structure. My results indicate that torus instability of the FR can be triggered at a relatively low critical height of : 8 Mm. This suggests that the quiet Sun’s FRs can easily overcome the confinement of the low coronal magnetic field and enter the higher corona. However, further investigation is still needed to determine if the large-scale coronal mangetic fields above constrain these small-scale eruptions.
