The accelerated expansion of the Universe is one of the main discoveries of the past
decades, indicating the presence of an unknown component: the dark energy. Evidence of …

In this work, a spherically symmetric and static relativistic anisotropic fluid sphere solution of
the Einstein field equations is provided. To build this particular model, we have imposed …

In a spatially flat Friedmann-Lemaître-Robertson-Walker universe, we investigate a unified
cosmic fluid scenario endowed with bulk viscosity in which the coefficient of the bulk …

In this paper, we concern about the Riemann problem for compressible no‐slip drift‐flux
model which represents a system of quasi‐linear partial differential equations derived by …

The presence of massive gravitons in the field of massive gravity is considered an important
factor in investigating the structure of compact objects. Hence, we are encouraged to study …

In this paper, we study two different models of dark energy based on the Chaplygin gas
equation of state. The first model is the variable modified Chaplygin gas, while the second …

We study isotropic and slowly-rotating stars made of dark energy adopting the extended
Chaplygin equation-of-state. We compute the moment of inertia as a function of the mass of …

Abstract A flat FLRW (Friedmann–Lemaitre–Robertson–Walker) cosmological model with
perfect fluid comprising of variable Chaplygin gas (VCG) has been studied in the context of f …

In this paper we consider two models of quintessence scalar fields with different potentials.
Interaction with generalized cosmic Chaplygin gas is also investigated. Cosmological …
