论文摘要
208pb中子皮肤厚度的最新实验和攻击理论研究足够精确，可以告知中子星的状态方程。特别是，在正常核密度下，208pb中子皮肤厚度与中子物质的压力之间的强相关性导致对半径，潮汐变形的预测以及典型的1.4太阳能质量中子星的惯性矩和惯性矩。在目前的工作中，我们研究了208pb中子皮肤厚度对贝叶斯统计分析中中子星的散装特性的这些最新分析的相对影响。为了研究高度不确定的状态方程的作用，采用了两个国家方程的模型。从我们对核理论，核实验和对状态密集物质方程的观察性约束的结合分析中，我们发现以90％的可信度水平$ r_ {1.4} = 12.36^{+0.38} _ { - 0.73} $ 0.73} $ km的1.4 solar-mast-mass中性含量中子， $ r_ {2.0} = 11.96^{+0.94} _ { - 0.71} $ km的半径为2.0太阳质量中子星，$λ_{1.4} = 440^{+103} _ {+103} _ {-144} $ for A TIDAL SOL ANTID SOL-SOL ANDIND SOL ANDIND SOL ARMASS SOR，和1.4 SOLARS MASS SOR，和1.4 $ i_ {1.338} = 1.425^{+0.074} _ { - 0.146} \，\ times 10^{45} \，\ rm {g \，cm}^{2}^{2} $在PSR J0737-3039a的intera inter inters in ass iss.38 as is 1.38 as 1.338
Recent experimental and ab initio theory investigations of the 208Pb neutron skin thickness are sufficiently precise to inform the neutron star equation of state. In particular, the strong correlation between the 208Pb neutron skin thickness and the pressure of neutron matter at normal nuclear densities leads to modified predictions for the radii, tidal deformabilities, and moments of inertia of typical 1.4 solar-mass neutron stars. In the present work, we study the relative impact of these recent analyses of the 208Pb neutron skin thickness on bulk properties of neutron stars within a Bayesian statistical analysis. Two models for the equation of state prior are employed in order to study the role of the highly uncertain high-density equation of state. From our combined Bayesian analysis of nuclear theory, nuclear experiment, and observational constraints on the dense matter equation of state, we find at the 90% credibility level $R_{1.4}=12.36^{+0.38}_{-0.73}$ km for the radius of a 1.4 solar-mass neutron star, $R_{2.0}=11.96^{+0.94}_{-0.71}$ km for the radius of a 2.0 solar-mass neutron star, $Λ_{1.4}=440^{+103}_{-144}$ for the tidal deformability of a 1.4 solar-mass neutron star, and $I_{1.338}=1.425^{+0.074}_{-0.146}\, \times 10^{45}\,\rm{g\,cm}^{2}$ for the moment of inertia of PSR J0737-3039A whose mass is 1.338 solar masses.
