Merger of black hole-neutron star binaries: Nonspinning black hole case

We perform a simulation for merger of a black hole (BH) -neutron star (NS) binary in full general relativity preparing a quasicircular state as initial condition. The BH is modeled by a moving puncture with no spin and the NS by the -law equation of state with =2. Corotating velocity field is assumed for the NS. The mass of the BH and the rest-mass of the NS are chosen to be 3. 2M_ and 1. 4M_ with relatively large radius of the NS 14 km. The NS is tidally disrupted near the innermost stable orbit but 80% of the material is swallowed into the BH with small disk mass 0. 3M_ even for such small BH mass 3M_. The result indicates that the system of a BH and a massive disk of M_ is not formed from nonspinning BH-NS binaries, although a disk of mass 0. 1M_ is a possible outcome.
