论文摘要
NS内核内的新短途物理学的可能性被纳入由Quark-Meson耦合模型产生的状态方程中。这种新物理学对能量密度的贡献与所涉及的桶芯之间的重叠量成正比。在饱和密度下对称核物质的性质没有变化，包括与巨型单极共振的数据兼容的不可压缩性，即使包括Hyperons，也可以维持最大质量$ M_ {Max}> 2.1 $ M $ _ \ odot $的中子星。
The possibility of new short-distance physics applicable inside the cores of NS is incorporated into the equation of state generated by the quark-meson coupling model. The contribution of this new physics to the energy density is taken to be proportional to the amount of overlap between the quark cores of the baryons involved. With no change to the properties of symmetric nuclear matter at saturation density, including an incompressibility compatible with data on giant monopole resonances, one can sustain neutron stars with a maximum mass $M_{max}>2.1$ M$_\odot$, even when hyperons are included.
