摘要:

用广义相对论模拟方法研究了双中子星合并坍缩到黑洞的引力波的特征。我们发现,GW光谱印记的合并动力学,形成过程的磁盘,状态方程的中子星,总质量和质量比。短$γ$射线爆发的中心引擎的形成机制,这可能是由一个黑洞和周围的磁盘,因此,可以通过GW的观测约束。

英文摘要:

We elucidate the feature of gravitational waves (GWs) from binary neutron star merger collapsing to a black hole by general relativistic simulation. We show that GW spectrum imprints the coalescence dynamics, formation process of disk, equation of state for neutron stars, total masses, and mass ratio. A formation mechanism of the central engine of short $γ$-ray bursts, which are likely to be composed of a black hole and surrounding disk, therefore could be constrained by GW observation.
