Gravitational deflection of light at 1{2/1} PPN order
Abstract
We compute in parametrized form the effect of source-velocity terms in the gravitational deflection of light. Internal rotation corresponds to sources of order ∈3 where in ^2 ∼ GM_ odot /R_ odot c^2 ∼ (v/c)^2 . We find for rigidly rotating models of the Sunand of Jupiter that, in each case, this effect is of order 10-6 arc sec. A very high accuracy that may be achievable by future space-bourne instruments is thus necessary for its detection.
