Violation of in Brans-Dicke gravity
Hoang Ky Nguyen, Bertrand Chauvineau
The Brans Class I solution in Brans-Dicke gravity is a staple in the study of gravitational theories beyond General Relativity. Discovered in 1961, it describes the exterior vacuum…
The complete exterior spacetime of spherical Brans-Dicke stars
Bertrand Chauvineau, Hoang Ky Nguyen
We derive the complete expression for the Brans Class I exterior spacetime explicitly in terms of the energy and pressures profiles of a stationary spherisymmetric gravity source.…
Impact of Star Pressure on in Modified Gravity beyond Post-Newtonian Approach
Hoang Ky Nguyen, Bertrand Chauvineau
We provide a concrete example exhibiting marked deviation from the PPN approximation in a modified theory of gravity. Specifically, we derive the exact formula for the Robertson pa…
New exact solution and anomaly in Brans-Dicke gravity with trace-carrying matter
Hoang Ky Nguyen, Bertrand Chauvineau
We present an exact static spherisymmetric solution for the Brans-Dicke action sourced by a self-gravitating massless Klein-Gordon helicity-0 field. In contrast to the Maxwell elec…
