标题： Studying the age of supergiant companions in the magnetized X-ray binaries

摘要： 多次提出利用高能质量X射线双星（HMXBs）中的中子星（NS），作为嵌入其超巨星（SG）伴星风供料中的轨道X射线探针，以限制超巨星的恒星线驱动风。我们演示了如何结合由风供料的NS产生的X射线吸积亮度的各种可观测量，以估计和限制供料者的年龄。这将有助于我们研究每个供料者模型的恒星演化路径。由于大质量恒星的演化本质上由质量损失决定，而由于风的微观结构未知，直接测量质量损失率存在重要的不确定性。 显示英文摘要

摘要： It has been proposed multiple times to use the neutron star (NS) in high-mass X-ray binaries (HMXBs) as an orbiting X-ray probe embedded in the wind-fed of its supergiant (SG) companion in order to constrain the stellar line-driven wind from the SG. We demonstrate how to combine various observables of HMXBs from the X-ray accretion luminosity produced by the wind-fed NS, in order to estimate and constrain the age of the donors. This would help us to study the stellar evolution track for each donor model. Since the evolution of massive stars is essentially determined by mass loss, and direct measures of mass-loss rates suffer from important uncertainties due to the unknown micro-structure of the wind.
