论文摘要
在这项工作中，我们研究了内壳对中子恒星总方程（EOS）的小贡献如何影响其质量 - 拉迪乌斯的关系，重点是规范质量为1.4 $ m_ \ odot $。我们在0.003 fm $^{ - 3}〜<〜n〜 <〜$ 0.08 fm $^{ - 3} $的范围内构建了这种类型的经验EO -$ p =kε^γ + b $ - 在该区域的声音速度。我们看到，声音速度的不同行为会影响规范恒星的半径超过1.1公里。该结果可以帮助我们理解极端结果，因为GW170817，其中一些研究表明规范恒星的半径不能超过11.9 km。
In this work we study how the small contribution of the inner crust to the total equation of state (EoS) of a neutron star affects its mass-radius relation, focusing on the canonical mass of 1.4$M_\odot$. We build empirical EoS of the kind - $p = Kε^γ + b$ - in the range of 0.003 fm$^{-3}~<~n~<~$0.08 fm$^{-3}$ and also calculate the speed of sound in this region. We see that different behaviours of the speed of sound can affect the radius of the canonical star by more than 1.1 km. This result can help us understand extreme results as GW170817, where some studies indicate that the radius of the canonical star cannot exceed 11.9 km.
