论文摘要
我们在存在非微耦合标量场的情况下研究球体对称和静态对象的结构，其$ V（ϕ）=-μ^2 ϕ^2/2+λϕ^4/4 $的电势。我们使用两个不同的状态方程来求解系统的数值方程，以提供中子物质的状态，并提供质量 - 拉迪乌斯关系以及标量场，密度和样本配置的质量函数的径向曲线。我们表明，在此类系统中遇到的特定解决方案类型导致特征性中子恒星质量 - 拉迪乌斯关系变成属于奇怪的夸克恒星的特定解决方案类型。
We study the structure of spherically symmetric and static objects in the presence of a nonminimally coupled scalar field having a potential of the form $V(ϕ)=-μ^2ϕ^2/2+λϕ^4/4$. We numerically solve equations of the system using two different realistic equations of state for neutron matter and give the mass-radius relations as well as the radial profiles of the scalar field, densities and the mass function for a sample configuration. We show that a specific solution type encountered in such systems causes characteristic neutron star mass-radius relations to turn into the ones belonging to strange quark stars.
