Can Solar System observations tell us something about the cosmological constant?
Lorenzo Iorio
Abstract
In this note we show that the latest determinations of the residual Mercury's perihelion advance, obtained by accounting for almost all known Newtonian and post-Newtonian orbital effects, yields only very broad constraints on the cosmological constant. Indeed, from δω=-0.0036 + - 0.0050 arcseconds per century one gets -2 10-34 km-2 < Lambda < 4 10-35 km-2. The currently accepted value for Lambda, obtained from many independent cosmological and large-scale measurements, amounts to almost 10-46 km-2.
