摘要:

我们使用一组新推导的有限温度状态方程的Brueckner-Hartree-Fock方法进行双中子星合并模拟。我们指出了重要的和相反的作用,有限的温度和旋转恒星的稳定性和系统的研究引力波的性质,物质分布,并在不同的情况下,在合并后阶段的喷出物的属性。几个普遍的关系的有效性也被检查,并确定最合适的EOS。

英文摘要:

We perform binary neutron star merger simulations using a newly derived set of finite-temperature equations of state in the Brueckner-Hartree-Fock approach. We point out the important and opposite roles of finite temperature and rotation for stellar stability and systematically investigate the gravitational-wave properties, matter distribution, and ejecta properties in the postmerger phase for the different cases. The validity of several universal relations is also examined and the most suitable EOSs are identified.
