论文摘要
在过去的二十年中，我们对$ \ Lessim $ \ Lessim $ 150 Myr的恒星人口的了解取得了巨大进展，该股票位于$ \ sim $ \ sim $ 100 $ 100 pc。大多数这样的恒星都在松散的运动组（“附近的年轻移动组”； Nymgs）中发现。 Nymgs及其成员的接近性促进了对固定前序列（Pre-MS）恒星以及单个Pre-MS系统的X射线特性的研究。在这篇综述中，我们关注NYMG X射线研究如何为恒星磁活动的早期演变，增生的X射线签名以及源自宿主Pre-MS星星的高能光子的辐射和耗散提供独特的见解。我们讨论了下一代X射线观察设施对Nymgs及其成员研究的这些方面的可能影响。
The past two decades have seen dramatic progress in our knowledge of the population of stars of age $\lesssim$150 Myr that lie within $\sim$100 pc of the Sun. Most such stars are found in loose kinematic groups ("nearby young moving groups"; NYMGs). The proximity of NYMGs and their members facilitates studies of the X-ray properties of coeval groups of pre-main sequence (pre-MS) stars as well as of individual pre-MS systems. In this review, we focus on how NYMG X-ray studies provide unique insight into the early evolution of stellar magnetic activity, the X-ray signatures of accretion, and the irradiation and dissipation of protoplanetary disks by high-energy photons originating with their host pre-MS stars. We discuss the likely impacts of the next generation of X-ray observing facilities on these aspects of the study of NYMGs and their members.
