Acesso em: 06 jul. 2023.2470-0029http://www.repositorio.ufop.br/jspui/handle/123456789/17243We revisit the decay of the orbital period in binary systems that occurs due to the emission of gravitational waves in the context of modifie- gravity models where the coupling Ggw between matter and on shell gravitons is allowed to differ from the Newton constant GN. Using the most precisely-timed double neutron star binary system, those of the double pulsar, we constrain the ratio Ggw=GN to the level of 10−4, improving by two orders of magnitude the present bound on this quantity.en-USrestritoArtigo publicado em periodicohttps://journals.aps.org/prd/abstract/10.1103/PhysRevD.107.064014https://doi.org/10.1103/PhysRevD.107.064014
