夸克星的结构:贝叶斯推断与神经网络建模的比较分析

Structure of Quark Star: A Comparative Analysis of Bayesian Inference and Neural Network Based Modeling

Silvia Traversi, Prasanta Char

摘要:

在这项工作中,我们比较了两个强大的参数估计方法,即贝叶斯推断和基于神经网络的学习研究夸克物质状态方程与常数声速参数化和结构的夸克星内的两个家庭的情况。我们使用的质量和半径的估计,从几个X射线源和质量和潮汐形变测量从引力波事件来约束我们的模型的参数。两种方法所得结果一致。预测的声速与共形极限相容。

英文摘要:

In this work, we compare two powerful parameter estimation methods namely Bayesian inference and Neural Network based learning to study the quark matter equation of state with constant speed of sound parametrization and the structure of the quark stars within the two-family scenario. We use the mass and radius estimations from several X-ray sources and also the mass and tidal deformability measurements from gravitational wave events to constrain the parameters of our model. The results found from the two methods are consistent. The predicted speed of sound is compatible with the conformal limit.
