红超巨星

红超巨星和AGB星的53.3微米吸收线轮廓中具有蓝移的填充发射特征，而HⅡ区的相应吸收线轮廓中具有红移的填充发射特征。

Red supergiants and AGB stars show a blue-shifted filling emission feature in their 53.3 μ m absorption line profile while H II regions show a red-shifted filling emission feature .

这在红超巨星脉塞源长基线干涉仪观测结果的分析中，还是首次获得成功。

So far as I know , this is the first successful analysis of the LBI observations on the maser sources of the red supergiant .

该星周尘可能是由红超巨星抛出物质所构成的大气层膨胀所致，这是大质量恒星演化的最后阶段。

The dust is likely formed as the swollen atmosphere of the supergiant sheds material into space , a final phase in the evolution of a massive star .

用双星技术（Binary－technique）的谱线分析方法来测定双星系统中的红巨星或红超巨星的星风物质损失率是目前最为精确的。

The binary-technique is the line profile analysis method which is the most accurate one being applied in a ζ Aur / VV Cep binary system to detect the mass-loss-rates of the stellar wind of the red-giant or of the red-super-giants .
