Abstract

In a recent paper [1], based on the data from the OMNI solar wind measurement database and our catalog of large-scale solar wind phenomena (ftp://ftp.iki.rssi.ru/pub/omni/ [2]), it was shown that magnetic clouds contain an electric current with an elevated content of helium ions in the center of the event interval, while in Ejecta such structures are not observed. From simple geometric considerations, an upper estimate is obtained for the size of the cross section of the electric current, which is equal to ~10% of the linear size of the cross section of the magnetic cloud.

磁性云中高氦丰度的电流大小的估计

摘要

在最近的论文[1]中，基于OMNI太阳风测量数据库中的数据和我们的大规模太阳风现象目录（ftp://ftp.iki.rssi.ru/pub/omni/ [2]）结果表明，在事件间隔的中心，磁云中的氦离子含量较高，而在Ejecta中未观察到这种结构。从简单的几何考虑，可以获得电流横截面大小的上限估计，该估计值等于磁云横截面线性大小的〜10％。
