Abstract:
For a general class of scalar-tensor theories of gravitation the properties of exact static spherically-symmetric vacuum and electrovac solution are discussed. On the other hand, post-Newtonian perfect fluid metric for this class of theories is found and compared with the exact vacuum solution. This comparison shows that the post-Newtonian approximation employs a special value of the scalar charge-mass ratio. This limitation is removed if a term involving scalar charge density is introduced explicitly into the initial Lagrangian. Observational consequences are discussed.- gravitation: radiation
