abstract

In this work we study numerically one kind of generalization of the Starobinsky inflationary model (power-law type), which is characterized by the parameter $p$. In order to find the parameter $p$ that fixes with observations, we compute the cosmological parameters $A_S$, $n_S$, and $r$ for several values of $p\simeq 1$. We have found that the value of $p=1.0004$ reproduces the value of $A_S$, $n_\sca$, and $r$ in agreement with current observational data.

  1. Exploring generalized Starobinsky Model of Inflation: Observational Constraints

    astro-ph.CO 2025-02 conditional novelty 3.0 of 10

    The power-law Starobinsky model is constrained to beta = 1.987 +0.013/-0.016 and log10 M = -4.72 +0.21/-0.20 at 95% CL, consistent with the standard R^2 model within 95% confidence.
