Add to ORKGThe chameleon mechanism appearing in massive tensor-scalar theory of gravity can effec-tively reduce the nonminimal coupling between the scalar field and matter. This mech-anism is invoked to reconcile cosmological data requiring introduction of Dark Energy with small-scale stringent constraints on General Relativity. In this communication, we present constraints on this mechanism obtained by a cosmological analysis (based on Supernovae Ia data) and by a Solar System analysis (based on PPN formalism)
