Tachyon warm inflationary universe model in the weak dissipation regimen
- 1. Instituto de Fisica, Pontificia Universidad Catolica de Valparaiso, Casilla 4059, Valparaiso (Chile)
Description
Warm inflationary universe model in a tachyon field theory is studied in the weak dissipation regimen. We develop our model for an exponential potential and a dissipation parameter Γ = Γ0 = constant. We describe scalar and tensor perturbations for this scenario. Also, we use recent astronomical observations for constraining the parameters appearing in our model.
