TYPE Ⅲ BURST SOURCES IN THE CORONA AND COMPARISONS WITH THE INTERPLANETARY MAGNETIC FIELD LINES
-
摘要: 本文将NancayMarkⅢ射电日像仪1980年3月至1981年9月高空间、高时间分辨率观测资料作了处理,发现日冕中大多数Ⅲ型爆发源都集中在黄道面附近；分布在黄道面北面的Ⅲ型爆发多于南面,西面多于东面；92.0%的Ⅲ型爆发源分布在黄纬40°以内。这些源与同期的ISEE-3飞船射电频谱仪获得的行星际磁场线相比对,发现行星际磁场的黄纬分布同Ⅲ型爆发源的分布有明显的对应关系。证实了行星际Ⅲ型爆发与日冕中的Ⅲ型爆发源的密切关系。Abstract: In thes paper, some high spacial and temperal resulation data observed with the Nancay Mark Ⅲ Radio heliograph in the period of 1980 March-1981 September are processed. It is found that a great number of Type Ⅲ burst sources in the corona are centralized near the ecliptic. Type Ⅲ burst sonrces located in the north of the ecliptic are larger in number than those in the south; the west are larger in number than the east. For 92.0% Type Ⅲ burst sonrces are located within 40°of the ecliptic. After a comparison with the interplanetary magnetic field lines obtained with the radio spectrograph on board ISEE-3 in the same period, it is discovered that there are clear corresponding relations on latitude distribution between Type Ⅲ burst sonrces in the corona and the interplanetary magnetic field lines. It is evidene that the interplanetary Type Ⅲ burst sources originate from Type Ⅲ burst sources in the corona.
