Sh2 -132是一个位于仙王座发射星云。它位于仙王座的南缘,距蝎虎座边界不远,沿着银河系平面;最适合在夜空中进行观测的时期是七月到十二月之间,这对于北半球陆地地区的观测者来说非常方便。

物理性质

Sh2-132距离地球约3,200秒差距(10,370光年),位于仙王座OB1区域的英仙臂内,这是巨大而明亮的OB星协。电离气体的恒星非常热且质量大。特别是两颗沃尔夫-拉叶星—HD 211564和HD 211853(后者也缩写为 WR 153)及一颗光谱级O8.5V的恒星和大约十颗 B 级恒星。O级恒星和一颗沃尔夫-拉叶星在光带中延伸出清晰可见的气泡无线电波—Shell B,可能源自两颗大质量恒星的星风。类似但较小的结构Shell A中心附近有一颗K级恒星。
