| 英文摘要 | Using high spatial and temporal data from the New Vacuum Solar Telescope and the Solar Dynamics Observatory, we present unambiguous observations of recurrent two-sided loop jets caused by magnetic reconnection between erupting minifilaments and a nearby large filament. The observations demonstrate that three two-sided loop jets, which ejected along the large filament in opposite directions, were similar in appearance and originated from the same region. We find that a minifilament erupted and drove the first jet. It reformed at the same neutral line later, and then underwent partial and total eruptions, driving the second and third jets, respectively. In the course of the jets, cool plasma was injected into the large filament. Furthermore, persistent magnetic flux cancellation occurred at the neutral line under the minifilament before its eruption and continued until the end of the observation. We infer that magnetic flux cancellation may account for building and then triggering the minifilament to erupt to produce the two-sided loop jets. This observation not only indicates that two-sided loop jets can be driven by minifilament eruptions, but also sheds new light on our understanding of the recurrent mechanism of two-sided loop jets. |
