该研究定量分析了MSP驱动的蒸发对Huntsman系统形成演化的影响，明确其仅起次要作用，还揭示了蒸发对低质量端白矮星质量-轨道周期关系的系统性偏移效应。
AI 中文摘要
Huntsman系统是新近发现的一类罕见毫秒脉冲星（MSP）双星子类型，其特征为拥有一颗分离的中子星与一颗演化的巨星伴星，且处于相对宽的轨道中。此前研究提出其形成涉及红 bump 诱导的分离，但该演化阶段中MSP驱动的蒸发的影响尚未被定量评估。本文定量研究了MSP驱动的蒸发对Huntsman系统形成与演化的影响，并评估其对可观测性质的作用。我们在宽范围初始双星参数下开展了包含MSP驱动蒸发的详细双星演化计算，并结合双星种群合成来预测Huntsman系统的可观测种群。研究发现，Huntsman系统主要起源于经历B型质量转移和红 bump 诱导分离的双星，初始供体质量为1.0-2.5倍太阳质量，轨道周期高于分岔周期。蒸发仅起次要作用，会轻微改变轨道演化和分离阶段的持续时间，但不会显著改变形成参数空间或预期种群，后者包含约10个Huntsman系统。我们进一步表明，蒸发可在低质量端系统性改变白矮星质量-轨道周期关系，导致给定白矮星质量下最终轨道系统性更宽。
英文摘要
Huntsman systems are a recently identified and rare subclass of millisecond pulsar (MSP) binaries, characterized by a detached neutron star and an evolved giant companion in relatively wide orbits. Their formation has been proposed to involve red-bump-induced detachment, whereas the influence of MSP-driven evaporation during this evolutionary stage has not yet been quantitatively assessed. We quantify the influence of MSP-driven evaporation on the formation and evolution of Huntsman systems and assess its effects on their observable properties. We performed detailed binary evolution calculations including MSP-driven evaporation over a wide range of initial binary parameters and combined them with binary population synthesis to predict the observable population of Huntsman systems. We find that Huntsman systems originate primarily from binaries undergoing Case B mass transfer and red-bump-induced detachment, with initial donor masses of $1.0-2.5\ M_\odot$ and orbital periods above the bifurcation period. Evaporation has a secondary effect, slightly modifying the orbital evolution and the duration of the detached phase, but does not significantly alter the formation parameter space or the expected population, which contains about 10 Huntsman systems. We further show that evaporation can produce systematic shifts in the white dwarf mass-orbital period relation at the low-mass end, leading to systematically wider final orbits for a given white dwarf mass.
