中子星中超软对称能遭遇非牛顿引力
Super-soft symmetry energy encountering non-Newtonian gravity in neutron stars
摘要:
考虑到大统一理论中提出的非牛顿引力,我们证明了中子星的稳定性和观测到的整体性质不能排除超饱和密度下的超软核对称性能量.利用与现有地球实验室数据一致的富中子核物质状态方程(EOS)估计了中子星可能违反引力平方反比定律的程度。
英文摘要:
Considering the non-Newtonian gravity proposed in the grand unification theories, we show that the stability and observed global properties of neutron stars can not rule out the super-soft nuclear symmetry energies at supra-saturation densities. The degree of possible violation of the Inverse-Square-Law of gravity in neutron stars is estimated using an Equation of State (EOS) of neutron-rich nuclear matter consistent with the available terrestrial laboratory data.
