标题： The Final Fate of Coalescing Binary Neutron Stars: Collapse to a Black Hole?

摘要： 具有中子星（NS）或黑洞（BH）组分的合并致密双星是当前正在建设中的激光干涉探测器的重要引力波源，也可能是在宇宙距离上的伽马射线暴的来源。 本文重点研究中子星-中子星双星的最终流体动力学合并和碰撞，并探讨这些系统最终形成黑洞是否是不可避免的命运。 显示英文摘要

摘要： Coalescing compact binaries with neutron star (NS) or black hole (BH) components are important sources of gravitational waves for the laser-interferometer detectors currently under construction, and may also be sources of gamma-ray bursts at cosmological distances. This paper focuses on the final hydrodynamic coalescence and merger of NS--NS binaries, and addresses the question of whether black hole formation is the inevitable final fate of these systems.
