Zipper reconnection has been proposed as a mechanism for creating most of the twist in the flux tubes that are present prior to eruptive flares and coronal mass ejections. We have conducted a first numerical experiment on this new regime of reconnection, where two initially untwisted parallel flux tubes are sheared and reconnected to form a large flux rope. We describe the properties of this experiment, including the linkage of magnetic flux between concentrated flux sources at the base of the simulation, the twist of the newly formed flux rope, and the conversion of mutual magnetic helicity in the sheared pre-reconnection state into the self-helicity of the newly formed flux rope.

由于剪切和拉链重新连接而形成磁通绳

拉链重连已被提议作为在爆发耀斑和日冕物质抛射之前存在的通量管中产生大部分扭曲的机制。我们对这种新的重新连接机制进行了首次数值实验，其中两个最初未扭转的平行磁通管被剪切并重新连接以形成大磁通绳。我们描述了该实验的特性，包括模拟基础上集中磁通源之间的磁通量链接、新形成的磁绳的扭转以及剪切预重联状态下互磁螺旋度的转换。新形成的磁通绳的自螺旋性。
