论文摘要
本文在大规模的布兰斯 - 迪克理论的背景下研究了各向异性奇怪的夸克恒星的存在和特性。通过使用MIT袋模型假设合适的电势函数，在Jordan框架中构建了场方程。我们采用嵌入一级方法以及连接条件来确定未知的度量函数。通过观察到的质量，对于袋子常数的不同值，可以预测奇怪的星形候选者LMC X-4的半径。我们分析了耦合参数以及标量场对状态决定因素的影响，并对球形系统的稳定性和可行性进行了多次检查。可以得出结论，所得的恒星结构在满足能量条件以及基本稳定标准的情况下在物理上可行和稳定。
This paper investigates the existence and properties of anisotropic strange quark stars in the context of massive Brans-Dicke theory. The field equations are constructed in Jordan frame by assuming a suitable potential function with MIT bag model. We employ the embedding class-one approach as well as junction conditions to determine the unknown metric functions. Radius of the strange star candidate, LMC X-4, is predicted through its observed mass for different values of the bag constant. We analyze the effects of coupling parameter as well as mass of scalar field on state determinants and execute multiple checks on the stability and viability of the spherical system. It is concluded that the resulting stellar structure is physically viable and stable as it satisfies the energy conditions as well as essential stability criteria.
