Abstract: Solar jets are collimated plasma ejections driven by magnetic reconnection, which play a critical role in the energy release and mass transport in the solar atmosphere. Using Solar Orbiter's Extreme Ultraviolet Imager (EUI) with its unprecedented spatiotemporal resolution, we report the discovery of nine transient coronal jets associated with a filament eruption on September 30, 2024. These jets, with a median lifetime of only 22 seconds, have significantly shorter timescales than previously observed coronal jets. They exhibit diverse morphologies and properties, evolving through three distinct phases of the filament eruption: initiation, rise, and peak. The spatial and temporal distribution of the jets suggests they are driven by dynamic magnetic reconnection between the erupting filament and overlying magnetic fields. These jets represent a distinct class of phenomena different from traditional mini-filament-driven jets, being directly associated with large-scale filament eruption processes. This study reveals a previously unrecognised class of highly transient jets, highlighting the complexity of reconnection-driven processes during filament eruptions and underscoring the importance of high-resolution observations in uncovering fundamental plasma dynamics in the solar atmosphere.

Abstract: 太阳喷流是由磁重联驱动的准直等离子体喷射，在太阳大气的能量释放和质量传输中起着关键作用。 利用太阳轨道器的极端紫外成像仪（EUI）前所未有的时空分辨率，我们报告了在2024年9月30日与一个丝状体爆发相关的九个瞬态日冕喷流的发现。 这些喷流的中位寿命仅为22秒，其时间尺度显著短于之前观测到的日冕喷流。 它们表现出多样的形态和特性，经历了丝状体爆发的三个不同阶段：启动、上升和峰值。 喷流的空间和时间分布表明它们是由爆发的丝状体与上覆磁场之间的动态磁重联驱动的。 这些喷流代表了一类不同于传统小丝状体驱动喷流的不同现象，直接与大尺度丝状体爆发过程相关。 这项研究揭示了一类此前未被认识到的高度瞬态喷流，突显了丝状体爆发期间重联驱动过程的复杂性，并强调了高分辨率观测在揭示太阳大气中基本等离子体动力学的重要性。
