We describe the discovery of a solar neighborhood (d=468pc) binary system with a main-sequence sunlike star and a massive noninteracting black hole candidate. The spectral...本研究报道了一个位于太阳邻域（solar neighborhood，距离d=468pc）的双星系统的发现，该系统由一颗主序星（main-sequence）阶段的类太阳恒星与一颗大质量无相互作用黑洞候选体（black hole candidate）组成。其光谱[...]
