We study the scalar field potential V(ϕ) in the scalar-tensor gravity with self-consistent polytropic stellar configurations. Without choosing a particular potential, we numerically derive the potential inside various stellar objects. We restrict the potential to conform to general relativity or to f(R) gravity inside and require the solution to arrive at SdS vacuum at the surface. The studied objects are required to obtain observationally valid masses and radii corresponding to solar type…

The realistic models of relativistic stars in f (R) = R + αR2 gravity

In the context of f(R)=R+αR2 gravity, we study the existence of neutron and quark stars for various α with no intermediate approximation in the system of equations. Analysis shows that for positive α

Simultaneous baldness and cosmic baldness and the Kottler spacetime

The uniqueness of the Kottler/Schwarzschild-de Sitter solution of the vacuum Einstein equations with positive cosmological constant is discussed and certain putative alternatives are shown to either

Collapsing spherical stars in f(R) gravity

We perform a careful investigation of the problem of physically realistic gravitational collapse of massive stars in f(R)-gravity. We show that the extra matching conditions that arise in the

TLDR
It is argued that a number of models in which the energy density of the scalar field red-shifts in a specific manner are studied could reconcile the low dynamical estimates of the mean mass density with the negligibly small spatial curvature preferred by inflation.

Constraining Newtonian stellar configurations in f(R) theories of gravity

Abstract We consider general metric f ( R ) theories of gravity by solving the field equations in the presence of a spherical static mass distribution by analytical perturbative means. Expanding the

INTRODUCTION TO MODIFIED GRAVITY AND GRAVITATIONAL ALTERNATIVE FOR DARK ENERGY

We review various modified gravities considered as gravitational alternative for dark energy. Specifically, we consider the versions of f(R), f(G) or f(R, G) gravity, model with non-linear

f(R) gravity and chameleon theories

We analyze f(R) modifications of Einstein's gravity as dark energy models in the light of their connection with chameleon theories. Formulated as scalar-tensor theories, the f(R) theories imply the

Stability analysis of spherically symmetric star in scalar - tensor theories of gravity

A stability analysis of a spherically symmetric star in scalar-tensor theories of gravity is given in terms of the frequencies of quasi-normal modes. The scalar-tensor theories have a scalar field

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

Stability of Polytropes

This paper is an investigation of the stability of some ideal stars. It is in- tended as a study in General Relativity, with emphasis on the coupling to matter, eventu- ally aimed at a better

MODIFIED F (R) GRAVITY CONSISTENT WITH REALISTIC COSMOLOGY: FROM A MATTER DOMINATED EPOCH TO A DARK ENERGY UNIVERSE

We develop the general scheme for modified f(R) gravity reconstruction from any realistic Friedmann-Robertson-Walker (FRW) cosmology. We formulate several versions of modified gravity compatible with

Evading equivalence principle violations, cosmological, and other experimental constraints in scalar field theories with a strong coupling to matter

We show that, as a result of nonlinear self-interactions, it is feasible, at least in light of the bounds coming from terrestrial tests of gravity, measurements of the Casimir force and those
