摘要
In this paper, we generate an anisotropic solution for a static sphere filled with quark matter in the framework of self-interacting Brans-Dicke theory. For this purpose, we add an anisotropic source in the seed distribution and decouple the field equations through deformation in the radial metric function. As a result of this transformation, the field equations are disintegrated into two systems which separately include the effects of isotropic and anisotropic sources. The system related to the additional source is solved via the MIT bag model equation of state. We consider Tolman V spacetime to formulate a solution for the isotropic sector which is extended to the anisotropic domain via decoupling technique. The junction conditions at the boundary determine the unknown parameters in terms of mass and radius of the spherical object. We investigate the viability and stability of the constructed strange star model in the presence of massive scalar field corresponding to the strange star candidate PSR J1614-2230. It is concluded that the anisotropic extension is well-behaved as it fulfills the necessary requirements of a physically acceptable model.
