论文摘要
我们描述了XSTAR光谱建模代码的原子数据库,总结了过去二十年中进行的系统升级,以实现来自具有原子数$ z \ leq 30 $的化学元件的k线建模,以及最近的扩展以处理高密度等离子体。在积聚磁盘的内部区域中发现了这样的等离子体环境,圆形紧凑物体(中子星和黑洞),它们会发出有关系统物理特性的丰富信息。我们的目的是提供可靠的建模工具,以利用新一代X射线太空望远镜(例如Xrism和Athena)的出色光谱功能,将在未来几年推出。讨论了数据策展方面,并编制了更新的参考资源列表,以改善数据库出处元数据。还描述了两个XSTAR衍生产品-ISMAB吸收模型和UADB数据库。
We describe the atomic database of the XSTAR spectral modeling code, summarizing the systematic upgrades carried out in the past twenty years to enable the modeling of K lines from chemical elements with atomic number $Z\leq 30$ and recent extensions to handle high-density plasmas. Such plasma environments are found, for instance, in the inner region of accretion disks round compact objects (neutron stars and black holes), which emit rich information about the system physical properties. Our intention is to offer a reliable modeling tool to take advantage of the outstanding spectral capabilities of the new generation of X-ray space telescopes (e.g., XRISM and ATHENA) to be launched in the coming years. Data curatorial aspects are discussed and an updated list of reference sources is compiled to improve the database provenance metadata. Two XSTAR spin-offs -- the ISMabs absorption model and the uaDB database -- are also described.
