Phys. Rev. D 77, 024037 (2008) [16 pages]Generalized Einstein-Aether theories and the Solar SystemReceived 24 July 2007; revised 30 October 2007; published 24 January 2008 It has been shown that generalized Einstein-Aether theories may lead to significant modifications to the nonrelativistic limit of the Einstein equations. In this paper we study the effect of a general class of such theories on the Solar System. We consider corrections to the gravitational potential in negative and positive powers of distance from the source. Using measurements of the perihelion shift of Mercury and time delay of radar signals to Cassini, we place constraints on these corrections. We find that a subclass of generalized Einstein-Aether theories is compatible with these constraints. © 2008 The American Physical Society URL:
