H-α谱线各部分的外展核大小
Sizes of flaring kernels in various parts of the H-alpha line profile
摘要：
在本文中，我们提出了新的结果的分光光度调查的耀斑内核的大小和它们的强度同时测量的H-α线轮廓的各个部分。我们的研究是基于波兰弗罗茨瓦夫大学Bialkow天文台的大型日冕仪（LC）、多通道减法双通摄谱仪和日食日冕成像系统（MSDP-SECIS）对太阳耀斑的高时间分辨率光谱成像观测。我们已经发现，所研究的单个耀斑核心的面积随时间和波长而变化，并且当在朝向H-α线的翅膀的连续波长中观察时，H-α耀斑核心的强度和面积系统地减小。我们的结果可以解释为磁环下部的锥形通道对色球等离子体的高能粒子束的激发效应。
英文摘要：
In this paper we present new results of spectraphotometrical investigations of the flaring kernels sizes and their intensities measured simultaneously in various parts of the H-alpha line profile. Our investigations were based on the very high temporal resolution spectral-imaging observations of the solar flares collected with Large Coronagraph (LC), Multi-channel Subtractive Double Pass Spectrograph and Solar Eclipse Coronal Imaging System (MSDP-SECIS) at Bialkow Observatory (University of Wroclaw, Poland). We have found that the areas of the investigated individual flaring kernels vary in time and in wavelengths as well as the intensities and areas of the H-alpha flaring kernels decreased systematically when observed in consecutive wavelengths toward the wings of the H-alpha line. Our result could be explained as an effect of the cone-shaped lower parts of the magnetic loops channeling high energy particle beams exciting chromospheric plasma.
