英文摘要	Solar filament eruptions are often characterized by stepwise evolution due to the involvement of multiple mechanisms, such as magnetohydrodynamic instabilities and magnetic reconnection. In this article, we investigated a confined filament eruption with a distinct two-stage evolution by using the imaging and spectroscopic observations from the Interface Region Imaging Spectrograph and the Solar Dynamics Observatory. The eruption originated from a kinked filament thread that separated from an activ e re gion filament. In the first stage, the filament thread rose slowly and was obstructed due to flux pile-up in its front. This obstruction brought the filament thread into reconnection with a nearby loop-like structure, which enlarged the flux rope and changed its connectivity through the foot-point migration. The newly formed flux rope became more kink unstable and dro v e the rapid eruption in the second stage. It ascended into the upper atmosphere and initiated the reconnection with the o v erlying field. Finally, the flux rope was totally disinte grated, producing sev eral solar jets along the o v erlying field. These observations demonstrate that the external reconnection between the flux rope and overlying field can destroy the flux rope, thus playing a crucial role in confining the solar eruptions. © 2024 The Author(s).
