【摘要】：超新星遗迹是超新星爆发后的残留物,包含爆发喷射物以及周围与其相互作用的物质;绿色延展天体是大质量恒星形成区候选体.这两类天体都与大质量恒星的形成与死亡有密切关系.本文尝试探究超新星遗迹与绿色延展天体的相互关系,以期对超新星是否促进大质量恒星形成这一问题有进一步了解.本研究通过计算得到14组超新星遗迹和绿色延展天体的相对距离,发现最小的也在百秒差距量级.通过分析274个超新星遗迹与298个绿色延展天体的空间分布,发现相对于其他区域,超新星遗迹附近的绿色延展天体明显多一些,但可能是因为超新星遗迹附近分子云密度大造成.斯必泽红外空间望远镜的巡天范围在银纬b=±1°内,在此范围以外的超新星遗迹附近的绿色延展天体是使用美国宇航局广角红外巡天探测器(WISE)巡天数据搜寻的,找到了4个绿色延展天体.得到的初步结论是超新星遗迹并不能直接促使绿色延展天体形成,但它们之间或许有间接联系.
[Abstract]:Supernova remains are remnants of supernova eruptions, including explosive jets and the surrounding interactions with them. Green extended objects are candidates for massive star formation regions. Both types of objects are closely related to the formation and death of massive stars. This paper attempts to explore the relationship between supernova relic and green extended celestial bodies in order to further understand whether supernovae promote the formation of massive stars. In this study, the relative distances of 14 groups of supernova relic and green extended celestial bodies were calculated, and the smallest one was found to be in the order of 100 seconds. By analyzing the spatial distribution of 274 supernova relic and 298 green extended celestial bodies, it is found that there are more green extended objects near supernova ruins than in other regions. But it is possible that the density of molecular clouds near the supernova remains is high. The Spitzer Infrared Space Telescope's survey range is within the silver latitude b = 卤1 掳. The green extended celestial body near the supernova remains outside this range is searched using NASA's Wide-Angle Infrared Survey Survey data. Four green extended objects were found. The preliminary conclusion is that supernova remnants do not directly promote the formation of green extended objects, but there may be an indirect link between them.
