- Abstract
- Gravitational light deflection in the Solar System can be detected by high precision astrometric measurements. We discuss the parametrized post-Newtonian framework and the comparison of metric theories of gravity. At the precision of a few micro-arcseconds, Gaia data will permit tests of the PPN parameters beta and gamma and to distinguish monopole and quadrupole gravitational light deflection. Accounting for relativistic effects is necessary to achieve the aimed for precision. The theoretical formulation of light deflection is discussed. We deduce an expression for the source direction derivatives required by the AGIS scheme in a simplified relativistic model. This model accounting for monopole and
quadrupole deflection terms has been... (More) - Gravitational light deflection in the Solar System can be detected by high precision astrometric measurements.
