Solar 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 motions and the cosmological constant: a new approach
In this paper we use the corrections to the Newton-Einstein secular precessions of the longitudes of perihelia ̟̇ of some planets (Mercury, Earth, Mars, Jupiter, Saturn) of the Solar System, phenomenologically estimated as solve-for parameters by the Russian astronomer E.V. Pitjeva in a global fit of almost one century of data with the EPM2004 ephemerides, in order to put on the test the express...
متن کاملSolar and stellar system tests of the cosmological constant
Some tests of gravity theories periastron shift, geodetic precession, change in mean motion and gravitational redshift are applied in solar and stellar systems to constrain the cosmological constant. We thus consider a length scale range from ∼ 10 to ∼ 10 km. Best bounds from the solar system come from perihelion advance and change in mean motion of Earth and Mars, Λ ∼ 10 km. Such a limit falls...
متن کاملCosmological Consequences of String-forming Open Inflation Models
We present a study of open inflation cosmological scenarios in which cosmic strings form betwen the two inflationary epochs. It is shown that in these models strings are stretched outside the horizon due to the inflationary expansion but must necessarily re-enter the horizon before the epoch of equal matter and radiation densities. We determine the power spectrum of cold dark matter perturbatio...
