SIMBAD资料

HD 150136是在南天天坛座,距离大约4,300年的一个多星系统 。它是天坛座OB1星协中的疏散星团NGC 6193内最亮的恒星。

系统

[编辑]

华盛顿双星目录中,列出HD 150136 有7个可见的成员分布在30弧秒内。成员A是一个紧密的三合星系统,包含3颗大质量的O型主序星。最亮的是有独自序号的成员C:HD 150135,距离仅有10弧秒。它是一颗O型光谱联星,也是NGC 5193的成员。其余的恒星与已知的NGC 6193的成员相似,亮度在10至12等之间[6]

主星是有双谱线的光谱联星 [4],在远处有第三颗伴星。第三颗伴星绕着这两颗恒星运行,轨道周期为8.2年,轨道离心率0.73,轨道倾角 108°。靠近的联星很难分离出各自的直径和轨道,但第三颗恒星分离的距离可以用甚大望远镜(VLTI)直接解析。在2012年测量的分离角是9微弧秒,相当于11-12天文单位[5]

性质

[编辑]

所有这3颗(包括HD 150135是4颗)最亮的恒星都是大质量且明亮的O型主序星,质量是太阳的33-63倍。它们的大小大约是踏阳的10倍,但温度是太阳的6-8倍,而每颗的亮度都超过太阳的10万倍。主星是离太阳最近的O3型恒星,温度46,500K,视亮度是太阳的18,000倍。但由于它的高温,其所有波长的总光度大约是75万倍[3]
