什么是“余辉”与千新星的区别？
What is the difference between an afterglow and a kilonova?
千新星是并合放射性抛射物自身的辐射（光学/红外），余辉是喷流撞入周围介质产生的多波段辐射；两者时空与机制都不同，共同描绘并合全貌。
A kilonova is the optical/infrared glow of the merger's radioactive ejecta, while the afterglow is multi-wavelength radiation from the jet slamming into surrounding matter; different in time, place and mechanism, together they paint the merger.

什么是“最重中子星”与“最轻黑洞”的质量鸿沟？
What is the mass gap between the heaviest neutron stars and lightest black holes?
观测显示中子星质量上限约2.3倍太阳质量、最小黑洞约5倍太阳质量，中间约3倍区间罕见，这一“质量鸿沟”暗示并合或超新星机制仍有未知。
Observations show neutron stars top out near 2.3 solar masses and the lightest black holes start near 5, leaving a rare 'gap' around 3 solar masses that hints at unknown merger or supernova physics.

双中子星并合会产生短伽马射线暴吗？
Do binary neutron-star mergers produce short gamma-ray bursts?
是的。并合抛出的物质形成千新星，而沿自转轴方向的相对论喷流产生短伽马暴；GW170817在引力波后1.7秒就探测到对应的伽马暴。
Yes. The merger ejects a kilonova, and a relativistic jet along the spin axis produces a short gamma-ray burst; for GW170817 the corresponding burst was seen just 1.7 seconds after the gravitational waves.
