Solar and stellar system tests of dark matter and cosmological constant. |
Abstract _ |
Some classical tests of gravity theories are applied in solar and stellar systems to constrain the cosmological constant and the local dark matter density. Best bounds from the solar system come from perihelion advance and change in mean motion of Earth and Mars. Limit fall very short to estimates from observational cosmology analyses but future experiments performing radio ranging observations of outer planets could improve it by several orders of magnitude. |
