Abstract

Neutron star low-mass X-ray binaries accrete via Roche-lobe overflow from a stellar companion that is ≲ 1 M_⊙. The accretion disk in these systems can be externally illuminated by X-rays that are reprocessed by the accreting material into an emergent reflection spectrum comprised of emission lines superimposed onto the reprocessed continuum. Due to proximity to the compact object, strong gravity effects are imparted to the reflection spectrum that can be modeled to infer properties of the NS itself and other aspects of the accreting system. This short review discusses the field of reflection modeling in neutron star low-mass X-ray binary systems with the intention to highlight the work that was awarded the 2023 AAS Newton Lacy Pierce Prize, but also to consolidate key information as a reference for those entering this subfield.

中子星低质量X射线双星吸积的反思

中子星低质量 X 射线双星是通过罗氏环溢出的方式从≲ 1 M⊙的恒星伴星吸积而来的。这些系统中的吸积盘可能会受到外部 X 射线的照射，而吸积物质会将这些 X 射线再处理成由叠加在再处理连续面上的发射线组成的新兴反射光谱。由于靠近紧凑天体，反射光谱会受到强大的重力影响，可以通过建模来推断 NS 本身以及增生系统其他方面的特性。这篇简短的综述讨论了中子星低质量 X 射线双星系统中的反射建模领域，意在重点介绍获得 2023 年美国天文学会牛顿-莱西-皮尔斯奖的研究成果，同时也是为了整合关键信息，为进入该子领域的研究人员提供参考。

期刊介绍： Astrophysics and Space Science publishes original contributions and invited reviews covering the entire range of astronomy, astrophysics, astrophysical cosmology, planetary and space science and the astrophysical aspects of astrobiology. This includes both observational and theoretical research, the techniques of astronomical instrumentation and data analysis and astronomical space instrumentation. We particularly welcome papers in the general fields of high-energy astrophysics, astrophysical and astrochemical studies of the interstellar medium including star formation, planetary astrophysics, the formation and evolution of galaxies and the evolution of large scale structure in the Universe. Papers in mathematical physics or in general relativity which do not establish clear astrophysical applications will no longer be considered. The journal also publishes topically selected special issues in research fields of particular scientific interest. These consist of both invited reviews and original research papers. Conference proceedings will not be considered. All papers published in the journal are subject to thorough and strict peer-reviewing. Astrophysics and Space Science features short publication times after acceptance and colour printing free of charge.
