Microfilament-Eruption Mechanism for Solar Spicules

Abstract: Recent studies indicate that solar coronal jets result from eruption of small-scale filaments, or “minifilaments” (Sterling et al. 2015, Nature, 523, 437; Panesar et al. ApJL, 832L, 7). In many aspects, these coronal jets appear to be small-scale versions of long-recognized large-scale solar eruptions that are often accompanied by eruption of a large-scale filament and that produce solar flares and coronal mass ejections (CMEs). In coronal jets, a jet-base bright point (JBP) that is often obs…
