我们继续我们的研究的双中子星星参数空间的影响，调查的自旋取向的动力学，引力波发射，和质量喷射过程中的双中子星星合并。我们模拟七种不同的配置，使用多种分辨率，以允许合理的错误评估。由于设置的特定选择，五种配置显示了进动效应，其中两种显示了轨道平面的进动（“摆动”），而三种显示了“摆动”运动;即，轨道角动量不进动，而轨道平面沿着轨道角动量轴运动。考虑到质量的喷射，我们发现旋进系统可能具有各向异性的质量喷射，这可能导致所研究的系统的最终残余踢。此外，对于所选择的配置，反对齐自旋导致更大的质量比对齐自旋喷出物，因此，可以预期这些配置的更明亮的电磁对应物。最后，我们比较了我们的模拟与进动，潮汐波形approximanymrphenompv2_nrtidalv2和发现之间的近似和我们的数值相对论波形的相位差低于1.2拉德积累在lastgravitational wave cycle。
We continue our study of the binary neutron star parameter space by investigating the effect of the spin orientation on the dynamics, gravitational wave emission, and mass ejection during the binary neutron star coalescence. We simulate seven different configurations using multiple resolutions to allow a reasonable error assessment. Due to the particular choice of the setups, five configurations show precession effects, from which two show a precession (“wobbling”) of the orbital plane, while three show a “bobbing” motion; i.e., the orbital angular momentum does not precess, while the orbital plane moves along the orbital angular momentum axis. Considering the ejection of mass, we find that precessing systems can have an anisotropic mass ejection, which could lead to a final remnant kick offor the studied systems. Furthermore, for the chosen configurations, antialigned spins lead to larger mass ejecta than aligned spins, so that brighter electromagnetic counterparts could be expected for these configurations. Finally, we compare our simulations with the precessing, tidal waveform approximantimrphenompv2_nrtidalv2 and find good agreement between the approximant and our numerical relativity waveforms with phase differences below 1.2 rad accumulated over the lastgravitational wave cycles.
