    • Abstract


      In this study, the irreversible thermodynamics of the universe in the framework of $f(R)$ gravity has been studied following standard Eckart theory of non-equilibrium thermodynamics. For a spatially flat universe, validity of GSLT and thermodynamic equilibrium have been examined both for apparent and eventhorizon as bounding horizons.The general result has been verified for exponential models of $f(R)$ gravity and it is shown that GSLT holds on both apparent and event horizon, but thermodynamic equilibrium does not holdon event horizon.

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
