$R^p$吸引子静态中子星现象学
$R^p$ Attractors Static Neutron Star Phenomenology
摘要：
本文在爱因斯坦框架下研究了$R^p$吸引子理论的中子星现象。Einstein框架$R^p$吸引子理论具有吸引子性质，它们起源于一大类具有任意非最小耦合的Jordan框架标量理论。这些理论在爱因斯坦框架提供了一个可行的类暴胀模型，并在这项工作中，我们调查他们的静态中子星的影响。我们数值求解的Tolman-Oppenheimer-Escheroff方程在爱因斯坦框架下，为三个不同的状态方程，我们提供了质量半径图的$R^p$吸引子理论的几种情况下的利益。我们面对的结果与特定质量的中子星的半径的几个及时的限制，正如我们所示，只有少数情况下对应于特定的状态方程通过严格的测试中子星现象。
英文摘要：
In this work we study the neutron star phenomenology of $R^p$ attractor theories in the Einstein frame. The Einstein frame $R^p$ attractor theories have the attractor property that they originate from a large class of Jordan frame scalar theories with arbitrary non-minimal coupling. These theories in the Einstein frame provide a viable class of inflationary models, and in this work we investigate their implications on static neutron stars. We numerically solve the Tolman-Oppenheimer-Volkoff equations in the Einstein frame, for three distinct equations of state, and we provide the mass-radius diagrams for several cases of interest of the $R^p$ attractor theories. We confront the results with several timely constraints on the radii of specific mass neutron stars, and as we show, only a few cases corresponding to specific equations of state pass the stringent tests on neutron stars phenomenology.
