Models of f R cosmic acceleration that evade solar system tests
We study a class of metric-variation f R models that accelerates the expansion without a cosmological constant and satisfies both cosmological and solar-system tests in the small-field limit of the parameter space. Solar-system tests alone place only weak bounds on these models, since the additional scalar degree of freedom is locked to the high-curvature general-relativistic prediction across ...
متن کاملSolar system tests of brane world models
The classical tests of general relativity (perihelion precession, deflection of light, and the radar echo delay) are considered for the Dadhich, Maartens, Papadopoulos and Rezania (DMPR) solution of the spherically symmetric static vacuum field equations in brane world models. For this solution the metric in the vacuum exterior to a brane world star is similar to the Reissner-Nordstrom form of ...
متن کاملSolar System tests disfavor f(R) gravities
Using the elegant method employed recently by Erickcek, Smith and Kamionkowski [1], on the premise that the space-time of Solar System is described by a metric with constant-curvature background added by a static perturbation, we show that many f(R) gravities are ruled out by Solar System tests.
متن کاملSolar system tests of the cosmological constant
— We discuss the influence of the cosmological constant Λ on the gravitational equations of motion of bodies with arbitrary masses and eventually solve the two-body problem. Observational constraints are derived from measurements of the periastron advance in stellar systems, in particular binary pulsars and the solar system. For the latter we consider also the change in the mean motion due to Λ...
متن کاملSolar System Tests of Higher-Dimensional Gravity
The classical tests of general relativity — light deflection, time delay and perihelion shift — are applied, along with the geodetic precession test, to the five-dimensional extension of the theory known as Kaluza-Klein gravity, using an analogue of the four-dimensional Schwarzschild metric. The perihelion advance and geodetic precession calculations are generalized for the first time to situat...
