稠密物质中的强子-夸克相变是否排除了大质量中子星的存在?

Does a hadron-quark phase transition in dense matter preclude the existence of massive neutron stars ?

摘要:

我们研究了强子-夸克相变对中子星最大质量的影响。状态方程的强子部分依赖于最新的Skyrme核能密度泛函,基本上适合于所有的实验核质量数据,并限制再现无限核物质的性质,从微观计算获得的现实力量。我们表明,由于相变的致密物质状态方程的软化不一定与大质量中子星的存在,如PSR J1614-2230不相容。

英文摘要:

We study the impact of a hadron-quark phase transition on the maximum neutron-star mass. The hadronic part of the equation of state relies on the most up-to-date Skyrme nuclear energy density functionals, fitted to essentially all experimental nuclear mass data and constrained to reproduce the properties of infinite nuclear matter as obtained from microscopic calculations using realistic forces. We show that the softening of the dense matter equation of state due to the phase transition is not necessarily incompatible with the existence of massive neutron stars like PSR J1614-2230.
