AI 中文摘要
G6096（盖亚DR3 609651611028044544）最近被报道为一个宽轨道（周期约450天）且偏心率约0.18的双星，可能包含一颗大质量白矮星或中子星。本文通过对蓝红波段间投影旋转速度、光谱解缠、联合径向速度和天体测量拟合以及X射线发射的分析，表明该系统包含额外可见成分而非致密天体。我们开发了一种联合建模光谱能量分布、旋转速度和天体测量的新方法来揭示G6096的本质。最后推测G6096是一个层级三体主序星系统，由一颗质量约0.75太阳质量的主星以及一个由两颗质量分别约0.62太阳质量和0.40太阳质量的矮星组成的内双星环绕。该方法应用于盖亚天体测量数据尤其是即将到来的DR4时，可能有助于揭示三体系统。
英文摘要
G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ($P\sim 450$ days) and eccentric ($e\sim0.18$) binary possibly hosting a massive white dwarf or neutron star. In this work, through analyses of the projected rotational velocity between the blue and red bands, spectral disentangling, joint radial velocity and astrometric fitting, and X-ray emission, we suggest that the system contains additional visible component(s) rather than a compact object. We develop a new approach to reveal the nature of G6096 by jointly modeling the spectral energy distribution, rotational velocity, and astrometric measurements. Finally, we speculate that G6096 is a hierarchical triple main-sequence star system, comprising a primary with a mass of $\sim 0.75\,M_\odot$ orbited by an inner binary consisting of two dwarfs with masses of $\sim 0.62\,M_\odot$ and $\sim 0.40\,M_\odot$, respectively. This method may help reveal a population of triple systems when applied to {\it Gaia} astrometric data, particularly the upcoming DR4.
