Warm inflation in general scalar-tensor theory of gravity

In this work, we investigate warm inflationary models in the context of a general scalar-tensor theory gravity which is coupled to radiation through dissipation term. We first derive potential exponential and hyperbolic tangent forms. consider parameter form $\Gamma = C_{1}T$ with $C_1$ being coupling focus only on strong regime interaction between inflaton fluid has been taken into account. compute observables constrain parameters our model using current Planck 2018 data. From analysis, discover that weak limit $\xi\ll 1$ needed order have derived $n_s$ $r$ consistent observational constraints. Particularly, scale $V_{0}$ models.
