Constraint on Prop erties of Rapidly Rotating Neutron Stars from Nuclear Symmetry Energy Slop e

Keywords： symmetry energy , neutron star , rotation

在过去的十余年中，对非对称核物质的对称能的研究无论从实验还是理论上都取得了较大的突破，这对中子结构及其物态方程的理解具有十分重要的意义。本研究将采用一个相对保守的对称能斜率范围(25 MeV 1.5M⊙)。

During the past decade, theoretical researches and terrestrial nuclear laboratory experiments have made impressive progresses on the researches of symmetry energy of the asymmetric nuclear matters, which is very important in understanding the equation of states and the structures of neutron stars. In this work, by making use of a conservative symmetry energy slope (SES) range (25 MeV1.5M⊙) of pulsar in low-mass X-ray binary EXO0748-676 if the observed redshift of this star is from the polar direction.
