Solar System tests disfavor f(R) gravities
نویسندگان
چکیده
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.

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 کاملAtmospheric Analysis of the M / L – and M / T – Dwarf Binary Systems LHS 102 and Gliese 229
We present 0.9—2.5μm spectroscopy with R∼800 and 1.12-1.22μm spectroscopy with R∼5800 for the M dwarfs Gl 229A and LHS 102A, and for the L dwarf LHS 102B. We also report IZJHKL′ photometry for both components of the LHS 102 system, and L′ photometry for Gl 229A. The data are combined with previously published spectroscopy and photometry to produce flux distributions for each component of the ki...
متن کاملSolar System constraints to general f ( R ) gravity
It has been proposed that cosmic acceleration or inflation can be driven by replacing the EinsteinHilbert action of general relativity with a function f(R) of the Ricci scalar R. Such f(R) gravity theories have been shown to be equivalent to scalar-tensor theories of gravity that are incompatible with Solar System tests of general relativity, as long as the scalar field propagates over Solar Sy...
متن کاملSolar System planetary orbital motions and f(R) Theories of Gravity
In this paper we study the effects of f(R) Theories of Gravity on Solar System gravitational tests. In particular, starting from an exact solution of the field equation in vacuum, in the Palatini formalism, we work out the effects that the modifications to the Newtonian potential would induce on the Keplerian orbital elements of the Solar System planets, and compare them with the latest results...
متن کاملConstraining the Schwarzschild-de Sitter Solution in Models of Modified Gravity
The Schwarzschild-de Sitter (SdS) solution exists in the large majority of modified gravity theories, as expected, and in particular the effective cosmological constant is determined by the specific parameters of the given theory. We explore the possibility to use future extended radio-tracking data from the currently ongoing New Horizons mission in the outskirts peripheries of the Solar System...
