利用IUE高分辨光谱研究气泡星云

Study of Bubble Nebula using IUE high resolution Spectra

M. Y. Anand, B. A. I Kagali, Jayant Murthy

摘要:

本文分析了气泡星云中心恒星(BD+602522)的IUE高分辨光谱。我们讨论了沿气泡视线方向不同区域的速度。我们发现,气泡星云比令人兴奋的恒星年轻(100倍),这表明气泡正在膨胀成不均匀的星际介质,或者恒星风的力学还没有完全理解。

英文摘要:

In this paper we have analyzed IUE high resolution spectra of the central star (BD+602522) of the Bubble nebula. We discuss velocities of the different regions along the line of sight to the bubble. We find that the Bubble Nebula is younger (by a factor of 100) than the exciting star suggesting that either the bubble is expanding into an inhomogenuous interstellar medium or that the mechanics of the stellar wind are not fully understood.
