Abstract
In this paper, we examine the salient features of anisotropic quark stellar model in the background of massive Brans–Dicke gravity. We use the MIT bag model along with Karmarkar condition to develop a model corresponding to Vaidya–Tikekar metric. The unknowns and the bag constant are computed through the matching conditions at the hypersurface. The solution is completely specified by employing the observed masses and radii of the strange star candidates. Further, we investigate the viability as well as stability of the spherical model. It is concluded that the predicted values of the bag constant corresponding to the viable and stable structure lie within the accepted range for the obtained solution in the context of massive Brans–Dicke theory.
