摘要

Coronal jets are always produced by magnetic reconnection between emerging flux and pre-existing overlying magnetic fields. When the overlying field is vertical/oblique or horizontal, the coronal jet will appear as anemone type or two-sided-loop type. Most observational jets are of the anemone type, and only a few two-sided-loop jets have been reported. Using the high-quality data from New Vacuum Solar Telescope, Interface Region Imaging Spectrograph, and Solar Dynamics Observatory, we present an example of two-sided-loop jets simultaneously observed in the chromosphere, transition region, and corona. The continuous emergence of magnetic flux brought in successively, the emergence of coronal loops and the slow rise of overlying horizontal filament threads. The following occurred sequentially: the deformation of the loops, the plasmoid ejection from the loop top, and pairs of loop brightenings and jets moving along the untwisting filament threads. All of the observational results indicate that magnetic reconnection exists between the emerging loops and the overlying horizontal filament threads, and it is the first example of two-sided-loop jets associated with ejected plasmoids and twisted overlying fields.
