Abstract
This paper is devoted to study self-gravitating spherically symmetric fluid
models in Brans–Dicke gravity. We formulate a set of equations which govern the
dynamics of evolving gravitating fluids through Weyl tensor, shear tensor, expansion
scalar, anisotropy, energy inhomogeneity, dissipation as well as scalar field. We also
discuss some particular cases according to different dynamical conditions. It is concluded
that fluid models for regular distribution of scalar field are consistent with
general relativity and models due to irregular distribution of scalar field deviate from
theory of general relativity.
