Dipartimento di Ingegneria, Universita’ del Sannio,Palazzo Dell’Aquila Bosco Lucarelli, Corso Garibaldi, 107 - 82100, Benevento, Italy.(Dated: January 4, 2011)We investigate the hydrostatic equilibrium of stellar structure by taking into account the modi-fied Lan´e-Emden equation coming out from f(R)-gravity. Such an equation is obtained in metricapproach by considering the Newtonian limit of f(R)-gravity, which gives rise to a modified Poissonequation, and then introducing a relation between…

Stellar structure model in hydrostatic equilibrium in the context of f ( R ) -gravity

In this work we present a stellar structure model from the f ( R ) -gravity point of view capable of describing some classes of stars (white dwarfs, brown dwarfs, neutron stars, red giants and the

Anisotropic Karmarkar stars in f(R, T)-gravity

The main aim of this work is devoted to studying the existence of compact spherical systems representing anisotropic matter distributions within the scenario of alternative theories of gravitation,

Physical Attributes of Bardeen Stellar Structures in f R Gravity

The main aim of our study is to explore some relativistic configurations of compact object solution in the background of f R gravity, by adopting the Krori-Barua spacetime. In this

Effects of CDTT model on the stability of spherical collapse in Palatini f(R) gravity

The objective of this paper is to study the stability of an adiabatic anisotropic collapsing sphere in the context of Palatini f(R) gravity. In this framework, we construct the collapse equation with

Study of charged stellar models in f(𝒢) gravity with Tolman–Kuchowicz space–time

In the context of modified [Formula: see text] gravity model, the current study highlights the effect of electric charge for static spherically symmetric stellar models in presence of anisotropic



f(R) Theories Of Gravity

Modified gravity theories have received increased attention lately due to combined motivation coming from high-energy physics, cosmology, and astrophysics. Among numerous alternatives to Einstein's

Relativistic stars in f(R) gravity

We study the strong gravity regime in viable models of so-called f (R) gravity that account for the observed cosmic acceleration. In contrast with recent works suggesting that very relativistic stars

The Newtonian limit of metric gravity theories with quadratic Lagrangians

The Newtonian limit of fourth-order gravity is worked out discussing its viability with respect to the standard results of general relativity. We investigate the limit in the metric approach which,

Models of f(R) Cosmic Acceleration that Evade Solar-System Tests

We study a class of metric-variation fRmodels that accelerates the expansion without a cosmological constant and satisfies both cosmological and solar-system tests in the small-field limit of the

Most general fourth-order theory of gravity at low energy

The Newtonian limit of the most general fourth-order gravity is performed with the metric approach in the Jordan frame with no gauge condition. The most general theory with fourth-order differential

Chameleon scalar fields in relativistic gravitational backgrounds

We study the field profile of a scalar field that couples to a matter fluid (dubbed a chameleon field) in the relativistic gravitational background of a spherically symmetric spacetime. Employing a

The landscape beyond Einstein gravity

The two main classes of ETGs considered in this book, scalar-tensor and f(R) gravity, are the subject of much of this chapter. After exposing the metric formalism, due consideration is given to the

Extended theories of gravity and their cosmological and astrophysical applications

Astrophysical observations are pointing out huge amounts of “dark matter” and “dark energy” needed to explain the observed large scale structure and cosmic dynamics. The emerging picture is a

The equation of motion for massive particles in f(R) modified theories of gravity is derived. By considering an explicit coupling between an arbitrary function of the scalar curvature, R, and the
