| 英文摘要 | Solar erupting prominences occasionally experience the splitting due to their interaction with ambient magnetic fields, yet the detailed process of the interaction remains elusive. As a result of the splitting, the significant part of prominence mass can evolve as a core of the associated coronal mass ejection (CME), while the rest of prominence mass is often transferred to and trapped in the nearby loop structure. Combining the high-quality multi-wavelength observations from SDO, ASO-S, FY-3E, and CALLISTO, we report an intriguing case of the splitting of an erupting prominence that occurred on 2023 December 31, and the splitting brought two different components of the core of the following CME, just like the "double-bang firecracker". During the splitting, the prominence apparently deflected southward from the initial quasi-radial direction and abruptly accelerated from ∼180 to ∼810 km s−1. Meanwhile, an unexpected newly-formed loop structure emerged from behind the ejecting prominence and propagated slowly along the quasi-radial direction. All results suggest that the inclined ejecting prominence and the quasi-radially propagating loop structure contributed to two separate components of the CME core. It is likely that the erupting prominence experienced external reconnection with nearby arcades, which resulted in the prominence splitting and the formation of the new loop structure that slowly erupted. The pseudostreamer configuration is proposed to play an important role in the case of "double-bang firecracker". © Science China Press 2025. |
