X-ray activity from different types of stars

X-ray emission is an important indicator of stellar activity. In this paper, we study stellar X-ray activity using the XMM-Newton and LAMOST data for different types of stars....X射线辐射（X-ray emission）是表征恒星活动的重要指标。本文利用XMM-牛顿卫星（XMM-Newton）与大天区面积多目标光纤光谱望远镜（LAMOST）的观测数据，针对不同类型恒星开展恒星X射线活动相关研究。
