Dark Energy Model in a Five-Dimensional Space-Time with a Massive Scalar Field

Abstract

The main aim of this investigation is to study the dynamical aspects of a cosmological model with dark energy (DE) and an attractive massive scalar field as source in a five dimensional spherically symmetric space-time. An exact solution of the field equations of general relativity is obtained which represents a massive scalar field DE model in five dimensions. The cosmological parameters of the model are computed and their dynamical behavior is studied. It is noted that our model is a quintessence model which represents accelerated expansion of the universe and is in good agreement with the recent cosmological observation.
