用扩展的相对论平均场模型研究中子星中的Pasta相

Pasta phases in neutron star studied with extended relativistic mean field models

Neha Gupta, P. Arumugam

摘要:

为了在相对论平均场模型中统一地解释有限核、无限物质和中子星的一些性质,重要的是用高阶耦合或密度依赖耦合来扩展它们。已知这些扩展在高密度区域具有强烈的影响。在这里,我们探讨他们的作用,在密度低于有限核的饱和密度的状态方程的相变与意大利面结构在地壳中的中子星。

英文摘要:

To explain several properties of finite nuclei, infinite matter, and neutron stars in a unified way within the relativistic mean field models, it is important to extend them either with higher order couplings or with density-dependent couplings. These extensions are known to have strong impact in the high-density regime. Here we explore their role on the equation of state at densities lower than the saturation density of finite nuclei which govern the phase transitions associated with pasta structures in the crust of neutron stars.
