Multiwavelength Study of 24 Equatorial Coronal-Hole Jets
Abstract
We studied 24 equatorial coronal-hole (ECH) jets using SDO/AIA and HMI observations on 27-28 June 2013 and 8-10 January 2014. Out of 24 jets (i) 16 jets (67%) are associated with mini-filament eruptions; (ii) 8 jets (34%) are triggered without mini-filament eruptions but with mini-flare arcades and other CME-like signatures; (iii) 5 jets (21%) are apparently associated with tiny flux-cancellation events at the polarity inversion line; (iv) 3 events are associated with sympathetic eruptions of filaments from neighboring jet source regions. The potential field extrapolations of the source regions reveal that almost all jets occurred in the fan-spine topology, and most of the events are in agreement with the breakout model of solar jets. We will present selected examples of each type, and discuss the implications for the jet energy-buildup and initiation mechanisms.
