| 摘 要： | 本文给出ＨＲ１０９９（Ｖ７１１Ｔａｕ）的高色散、高分辨率的分光观测结果。从观测结果分析，该双星系统的两子星均有剧烈的色球活动，强的Ｈα发射主峰主要来自活动性强的冷子星，谱线轮廓形状的大幅度变化取决于色球发射物质的运动和恒星内部的物理变化。

| Abstract: | HR1099 is a RS CVn system with high chromospheric activity. Its H-alpha line has an over continuous level emission, and the emission profile changes greatly with the orbital phase and activities in the chromosphere.Based on the observations obtained in Yunnan Observatory and McDonald Observatory in 1990 and 1984, raspectively, we give our explanation on the varing profile as follows,1) The H-alpha emission mainly emits from the cooler component, the main one.2) The mechanisms of the H-alpha emission formation are the photoionization and collision exitation.3) The dips on the emission profile are mainly due to movements of the chromospheric matter and cool plasma cloud caused by large starspots. |
