摘要
本文评述了1973年发现天体SiO脉泽谱线以来其观测和研究的进展。内容包括(1)天体SiO脉泽谱线的观测特征;(2)在恒星早期和晚期演化过程中SiO脉泽分子所起的作用和它们可能的状态;(3)利用SiO脉泽谱线的观测,研究晚型星拱星包层结构和速度流场、恒星质量损失率、速度频谱分析;(4)SiO脉泽时变特征的观测和研究。
The progress and current situation of observation and study on the spectra of celestial SiO maser since it was discovered in 1973 are reviewed in this paper. The content includes (1) the observational characteristics of the spectra of celestial SiO maser, (2) the roles which SiO maser molecules plays in early and late stages of star evolutionary process, and their possible state, (3) the results of theoretical study on the shell structure and velocity field of the circumstellar envelope, and the mass loss rate in late type star, and the analysis of spectra of velocity by the observation of the spectra of SiO maser, (4) the observation and study of the time variation of SiO maser.
