Abstract

The position of a mobile D-3 brane moving towards a stack of localized D-5 branes has been studied as a candidate driving inflation in the warm-inflationary scenario. Here we consider the dissipation parameter as an arbitrary function of only the inflaton field. We find that the observables remain well within PLANCK predictions for a range of model parameters. We also discuss the non-gaussianity generated during inflation in this model.
