  In this work, we generate two static anisotropic solutions for a sphere
containing 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 and Karmarkar condition to formulate two solutions for the isotropic
sector which are 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 models in the presence of massive
scalar field corresponding to three strange star candidates: Her X-1, PSR
J1614-2230 and 4U 1608-52. It is concluded that the anisotropic models are
well-behaved as they fulfill the necessary requirements for lower as well as
higher values of the decoupling parameter.
