“…[69][70][71] Now by setting k = 0 we can reduce GCG and also cosmological constant type dark energy EOS can be described under the specification n = −1 and h = 1 + k. Recently, many stable and viable models on physical characteristics of compact objects have been developed by using MCG EOS. [72][73][74][75][76][77] Based on the above background, the main motivation behind the choice of MCG for our study is to emphasize the effect of MCG on various physical attributes of a spherically symmetric dark energy stars. The rest of the paper is organised as follows : In Section 2, we have formulated the Einstein-Maxwell field equa-tions for a mixture of ordinary and dark matter fluid.…”

In the present article, we explore a new solution to the Einstein-Maxwell field equations to describe spherically symmetric, charged and anisotropic dark energy stars. The interior of such stars containing two non-interacting fluids like dark and normal matter with a relation that the dark energy density is proportional to the energy density of a isotropic matter. We have used modified chaplygin gas equation to define the dark energy part. Also we have defined the interior space-time through Krori-Barua (KB) space-time and matched it with the exterior Reissner-Nordström space-time. The well-behaveness of the physical attributes have been discussed by plotting graphs for three specific compact objects with respect to our solutions. We conclude that all the physical attributes satisfy the required conditions for viability as well as stability and hence our model can be used to characterize dark energy stars for a set of parametric values belong to the present study.

In this paper, our interest lies in investigating the possibilities of reconstructing analytical solutions for some familiar bouncing models in the flat Friedmann–Lemaître–Robertson–Walker (FLRW) geometry. We inspect the various gravitational Lagrangians, which are efficient enough for reproducing analytical solutions for symmetric, oscillatory, power law and bounce from loop quantum cosmology settings. Equation of state parameter, energy conditions, stability analysis have been performed for each model to examine its validity. The outcomes determine that the [Formula: see text] modified theory is the competitive candidate of extended theories on the cosmological scale.
