Description

The dissipative mechanism in warm inflation scenario can provide the inflating universe with a warm exit to the radiation dominated era rather than a supercooled exit to a reheating phase. In this work, we constrain the model parameters for warm inflation from Planck 2015 data. In addition, the reheating era can be optimized by varying the number of $e$-folds of inflation. Best fit values for the model parameters are estimated with and without the contribution to fluctuation from thermal excitations.
