论文摘要
在过去的几十年中,已经提出了不同全局物理量之间的许多普遍关系,以限制中子星的不可观察或难以观察的特性。但是很少有人与重力红移或重力结合能有关,尤其是对于快速旋转的中子星。在这里,我们将重点关注与这两个数量有关的普遍关系。基于正常或混合中子星的微观核多体型理论的预测,基于11个状态方程(EOSS),我们在三种旋转情况下提出了一组新的准宇宙关系:静态,一般旋转和开普勒旋转。这些新的准宇宙关系提供了一种潜在的方法来限制或估计中子星的不可观察或难以观察到的特性。
In the last few decades, lots of universal relations between different global physical quantities of neutron stars have been proposed to constrain the unobservable or hard to be observed properties of neutron stars. But few of them are related to the gravitational redshift or the gravitational binding energy, especially for the fast rotating neutron stars. Here we will focus on the universal relations related to these two quantities. Based on 11 equations of state (EOSs) from the predictions of microscopic nuclear many-body theories for normal or hybrid neutron stars, we proposed a set of new quasi-universal relations under three rotating cases: static, general rotating and Keplerian rotating. These new quasi-universal relations provide a potential way to constrain or estimate the unobservable or hard to be observed properties of neutron stars.
