We find that for a barotropic or linear equation of state (EoS) for the DE, p=wρ, and standard matter sector the corresponding CCDM model is described by the same functional structure of the ratio of particle production, Γ. For a different EoS the functional form of the Γ term is not longer maintained, however, in the case of a polytropic EoS given by the Chaplygin gas the resulting Γ term can be written as the one obtained in the barotropic case under certain considerations.enacceso abiertoAstronomy And AstrophysicsSpace And Planetary Sciencearticle
