Abstract

We study the effects of the nonminimal derivative coupling on the dissipativedynamics of the warm inflation where the scalar field is nonminimally coupled togravity via its kinetic term. We present a detailed calculation of the cosmologicalperturbations in this setup. We use the recent observational data from the jointdata set of WMAP9 + BAO + and also the Planck satellite data to constrain ourmodel parameters for natural and chaotic inflation potentials. We study also thelevels of non-Gaussianity in this warm inflation model and we confront the resultwith recent observational data from the Planck satellite.
