标题： Simultaneous detection of flare-associated kink oscillations and extreme-ultraviolet waves

摘要： 沿日冕环和日珥传播的扭振现象经常伴随极紫外（EUV）波出现，然而，关于两者之间的因果关系仍需进一步研究。本文报道了2023年3月3日X2.1级耀斑期间同时观测到的扭振和EUV波。这些扭振几乎垂直于环状结构的轴线，在三条日冕环和一条日珥中被探测到。其中一条短环在同一5.2分钟周期内显示了三个位置的同相振荡，这可能由膨胀环的推动触发，并被解释为驻波。发现短环与两条长环的扭振之间存在时间延迟，表明扭波在不同环中传播。一条长环和一条日珥的扭振可能由CME扰动驱动，而另一条长环的扭振可能归因于EUV波的相互作用。短环扭振的开始时间与EUV波的开始时间几乎相同，证明它们几乎是同时发生的。EUV波很可能由膨胀的环状结构激发，表现出两个成分：前导成分是快速的日冕波，后随成分可能是由于拉伸的磁力线导致的。 显示英文摘要

摘要： Kink oscillations, which are frequently observed in coronal loops and prominences, are often accompanied by extreme-ultraviolet (EUV) waves. However, much more needs to be explored regarding the causal relationships between kink oscillations and EUV waves. In this article, we report the simultaneous detection of kink oscillations and EUV waves that are both associated with an X2.1 flare on 2023 March 03 (SOL2023-03-03T17:39). The kink oscillations, which are almost perpendicular to the axes of loop-like structures, are observed in three coronal loops and one prominence. One short loop shows in-phase oscillation within the same period of 5.2 minutes at three positions. This oscillation could be triggered by the pushing of an expanding loop and interpreted as the standing kink wave. Time lags are found between the kink oscillations of the short loop and two long loops, suggesting that the kink wave travels in different loops. The kink oscillations of one long loop and the prominence are possibly driven by the disturbance of the CME, and that of another long loop might be attributed to the interaction of the EUV wave. The onset time of the kink oscillation of the short loop is nearly same as the beginning of an EUV wave. This fact demonstrates that they are almost simultaneous. The EUV wave is most likely excited by the expanding loop structure and shows two components. The leading component is a fast coronal wave, and the trailing one could be due to the stretching magnetic field lines.
