Abstract |
We consider a class of spherically symmetric and static Finsler spacetimes which are small perturbations of the Schwarzschild spacetime. The deviations from the Schwarzschild spacetime are coded into three perturbation functions. One of them, which we call the 'Finslerity', introduces a spatial anisotropy which is a genuine Finsler feature. We work out the equations of motion for freely falling particles and for light rays, i.e. the timelike and lightlike geodesics, in this class of spacetimes. Then we discuss the bounds placed on the perturbation functions, in particular on the Finslerity, by observations in the Solar system such as light deflection, perihelion precession and others. |
