太阳风中的冷密等离子体偶尔被探测到，但冷密等离子体的来源仍然是虚幻的。封闭场和附近开放场之间的交换重联（IR）有助于太阳风的形成。我们提出了一个封闭的灯丝喷发与2014年12月24日的喷状日冕物质抛射（CME）。由于连续的磁通量抵消和出现，暗条经历了连续的激活并最终爆发。被限制的爆发丝状体表现出明显的解捻运动，并且大部分丝状体物质回落。在爆发过程中，一些微小的斑点从被限制的灯丝体中逃逸出来，沿着新形成的开放场线扎根在灯丝的南端，一些明亮的等离子体从灯丝的北端流向附近开放场的偏远地点。新形成的开阔磁力线向南移动，并有多个分支。类似于泡芙的CME也显示出多个明亮的锋面和明显的南移。结果表明，在爆发暗条的封闭场和附近的开放场之间存在着间歇性的红外辐射，它释放出一部分暗条物质（团块），形成了喷烟状的CME。我们认为，红外线提供了一个可能的来源冷致密等离子体的太阳风。
The cold-dense plasma is occasionally detected in the solar wind with in situ data, but the source of the cold-dense plasma remains illusive. Interchange reconnections (IRs) between closed fields and nearby open fields are known to contribute to the formation of solar winds. We present a confined filament eruption associated with a puff-like coronal mass ejection (CME) on 2014 December 24. The filament underwent successive activations and finally erupted, due to continuous magnetic flux cancelations and emergences. The confined erupting filament showed a clear untwist motion, and most of the filament material fell back. During the eruption, some tiny blobs escaped from the confined filament body, along newly formed open field lines rooted around the south end of the filament, and some bright plasma flowed from the north end of the filament to remote sites at nearby open fields. The newly formed open field lines shifted southward with multiple branches. The puff-like CME also showed multiple bright fronts and a clear southward shift. All the results indicate an intermittent IR existed between closed fields of the confined erupting filament and nearby open fields, which released a portion of filament material (blobs) to form the puff-like CME. We suggest that the IR provides a possible source of cold-dense plasma in the solar wind.
