Abstract |
‎In this work, ‎tachyon scalar field is taken as inflaton for describing the constant-roll inflationary scenario. ‎The main difference of the mentioned scenario with the slow-roll inflation stands in description of the second sow-roll parameter so that it is assumed as a constant which is not required to be smaller than unity. ‎The assumption could result in a differential equation for the Hubble parameter. ‎Getting an analytical solution seems to be very difficult so the work will be pursuing with a numerical solution for the Hubble parameter. ‎The solution will be used to consider the behavior of the perturbation parameters during the inflationary times and the comparison with the observational data indicates that the model could suitably describe inflation. ‎The attractor feature will be considered as well to determine that the model could satisfy this feature. |
