Note on the reheating temperature in Starobinsky-type potentials

Abstract

AbstractThe relation between the reheating temperature, the number of e-folds and the spectral index is shown for the Starobinsky model and some of its descendants through a very detailed calculation of these three quantities. The conclusion is that for viable temperatures between 1 MeV and $$10^9$$ 10 9 GeV the corresponding values of the spectral index enter perfectly in its $$2\sigma $$ 2 σ C.L., which shows the viability of this kind of models.
