Abstract
This paper aims to analyzing the characteristics of a spherically symmetric relativistic star in the context of massive Brans-Dicke gravity. The system of field equations is derived for specific forms of coupling and potential functions by employing the MIT bag model. The unknown metric tensors are evaluated through a well-behaved function along with Karmarkar condition for class-one embedding. The value of the bag constant is computed with the help of junction conditions for the strange star candidate Her X-1. We examine trends of energy density and anisotropic pressure of the constructed model for specific values of the coupling parameter and corresponding predicted values of the bag constant. Finally, we discuss the physical viability and stability of the model through various tests. It is concluded that the obtained celestial structure is in agreement with the physical viability and stability criteria under the effect of a gravitational scalar field.
