AI 中文摘要
本文分析了有限温度物态方程对大质量Brans-Dicke理论以及symmetron、dilation筛选机制下白矮星平衡结构的影响，计算并给出了数值得到的质量-半径关系、有效引力常数，以及恒星内部标量场、压强和度规的径向分布。结果表明，假设非零温度会使白矮星半径增大，而恒星总质量基本不变，文中还讨论了有效引力常数、中心密度与恒星半径之间的相互作用。
英文摘要
In this article we analyze the effects of a finite temperature equation of state on the equilibrium structure of white dwarfs in massive Brans-Dicke theory as well as the symmetron and dilaton screening mechanisms. We compute and present the numerically obtained mass-radius relation, effective gravitational constant as well as radial profiles of the scalar field, pressure and metric within the star. We show that assuming a non-zero temperature effectively results in a larger radius while leaving the total mass of the star essentially unchanged, and discuss the interplay between the effective gravitational constant, central density, and radius of the star.
