论文摘要
在冠状气氛中重新连接期间注入太阳风中的磁通绳的结构是通过粒子中的模拟探索的，并将其与帕克太阳能探头的磁性“折返”的原位测量进行了比较。我们建议在电晕中的开放和闭合通量之间的多X线重新连接到太阳风中，并且这些通量绳索在长距离上向外对流，然后由于重新连接而侵蚀。探索太阳风中通量绳索的磁性结构的模拟重现了换回观测的以下关键特征：径向磁场快速旋转向横向方向，这是与强导磁场重新连接的结果；以及逆转径向场分量的潜力。讨论了在冠状气氛中注射大量通量绳的潜在影响，以理解太阳风的产生。
The structure of magnetic flux ropes injected into the solar wind during reconnection in the coronal atmosphere is explored with particle-in-cell simulations and compared with in situ measurements of magnetic "switchbacks" from the Parker Solar Probe. We suggest that multi-x-line reconnection between open and closed flux in the corona injects flux ropes into the solar wind and that these flux ropes convect outward over long distances before eroding due to reconnection. Simulations that explore the magnetic structure of flux ropes in the solar wind reproduce the following key features of the switchback observations: a rapid rotation of the radial magnetic field into the transverse direction, which is a consequence of reconnection with a strong guide field; and the potential to reverse the radial field component. The potential implication of the injection of large numbers of flux ropes in the coronal atmosphere for understanding the generation of the solar wind is discussed.
