Abstract.
This paper explores hydrodynamics and hydrostatic of a star in the post-Newtonian approximation of massive Brans-Dicke gravity. We study approximated solutions of the field equations up to \( O(c^{-4})\) and generalize Euler equations of motion. We then formulate equations governing the stability and instability of the system. Finally, we discuss spherically symmetric stars for a specific barotropic case like dust, cosmic string and domain wall in this scenario.
