    • Transit cosmological models with perfect fluid and heat flow in Sáez-Ballester theory of gravitation


      More Details Abstract Fulltext PDF

      In this paper, the Bianchi-V universe has been applied to the transitional universe. Exact solutions of Einstein’s modified field equations in the framework of Sáez-Ballester theory are obtained with heat conduction and perfect fluid. We have applied the hybrid expansion law for the average scale factor $a = kt^{\alpha} e^{\beta t}$, (where $\alpha \geq 0$, $k$ > 0, and $\beta \geq 0$ are constants). This results into a new class of transit models from deceleratinguniverse to the current accelerating universe. The present work also elucidates some of the physical, geometric and kinematic properties of the universe and found them in good agreement with recent observations.

      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.
