X-ray detections in the {sigma} Ori cluster

We investigated the X-ray emission from young stars and brown dwarfs in the {sigma} Orionis cluster ({tau}=~3Ma, d=~385pc) and its relation to mass, the presence of...我们针对猎户座σ星团（σ Orionis cluster，年龄τ≈3百万年，距离d≈385秒差距）内的年轻恒星与褐矮星（brown dwarfs）的X射线辐射（X-ray emission）展开了研究，并探讨了该辐射与恒星质量以及……之间的关联。
