Bayesian Analysis of Hybrid EoS based on Astrophysical Observational Data

David Alvarez-Castillo, Alexander Ayriyan, David Blaschke, Hovik Grigorian

摘要:

我们进行了贝叶斯分析的概率措施紧凑的恒星状态方程使用新的,分离的质量和半径的约束。分析使用一个简单的混合状态方程的参数化,调查的可能性,在紧凑型恒星的一阶解除禁闭过渡。后一个问题与在重离子碰撞中仔细研究的QCD相图中可能存在的关键终点有关。

英文摘要:

We perform a Bayesian analysis of probability measures for compact star equations of state using new, disjunct constraints for mass and radius. The analysis uses a simple parametrization for hybrid equations of state to investigate the possibility of a first order deconfinement transition in compact stars. The latter question is relevant for the possible existence of a critical endpoint in the QCD phase diagram under scrutiny in heavy-ion collisions.
