摘要:

在扩展的$σ$ - $ω$模型下,对中子星物质的朗道质量进行了贝叶斯分析.为此,我们考虑了PSR 0740+6620的质量测量,GW 170817的潮汐变形能力估计和PSR J 0030 +0451的质量半径估计。使用朗道质量作为理论的自由参数,我们依靠贝叶斯方法的预测能力来找到这个核量的最佳值。

英文摘要:

We present a Bayesian analysis of the Landau mass within the extended $σ$-$ω$ model for neutron star matter. To this purpose, we consider the mass measurement of the object PSR 0740+6620, the tidal deformability estimation from the GW170817 and the mass-radius estimate of PSR J0030+0451 by NICER. Using Landau mass as free parameter of the theory, we rely on the prediction power of the Bayesian method to find the best value for this nuclear quantity.
