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全局特性不能排除在超饱和密度下的超软核对称能。中子星中可能违反引力平方反比定律的程度是用与现有的地球实验室数据相一致的富中子核物质状态方程来估计的。
Considering the non-Newtonian gravity proposed in grand unification theories, we show that the stability and observed global properties of neutron stars cannot rule out the supersoft nuclear symmetry energies at suprasaturation densities. The degree of possible violation of the inverse-square law of gravity in neutron stars is estimated using an equation of state of neutron-rich nuclear matter consistent with the available terrestrial laboratory data.
