论文摘要
我们表明，可以通过即将进行的重力波观测来估计合并中子星的最大和最小质量。我们模拟二进制中子星信号的种群，并建模其质量分布，包括上下截止。如果质量分布支持质量接近截止的质量，则可以将下部（上）限制测量为$ \ sim 0.2（0.1）\ text {m} _ {\ odot} $，并以$ 50 $检测到$ 50 $检测。上质量限制为中子恒星状态方程的高密度特性提供了信息，而下限标志着中子恒星和白矮星之间的鸿沟。
We show that the maximum and the minimum mass of merging neutron stars can be estimated with upcoming gravitational wave observations. We simulate populations of binary neutron star signals and model their mass distribution including upper and lower cutoffs. The lower(upper) limit can be measured to $\sim 0.2(0.1)\text{M}_{\odot}$ with $50$ detections if the mass distribution supports neutron stars with masses close to the cutoffs. The upper mass limit informs about the high density properties of the neutron star equation of state, while the lower limit signals the divide between neutron stars and white dwarfs.
