چکیده

$f(Q)$ gravity is the extension of symmetric teleparallel general relativity (STGR), in which both curvature and torsion vanish attributed to nonmetricity. This work performs theoretical analyses static spherically solutions with an anisotropic fluid for gravity. We find that off-diagonal component field equation due a coincident gauge leads stringent restrictions on functional form In addition, although exact Schwarzschild solution only exists STGR, we obtain Schwarzschild-like nontrivial study its asymptotic behavior deviation from one.

Spherically Symmetric Solutions in a New Braneworld Massive Gravity Theory

In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...

Static spherically symmetric solutions for conformal gravity in three dimensions

Static spherically symmetric solutions for conformal gravity in three dimensions are found. Black holes and wormholes are included within this class. Asymptotically the black holes are spacetimes of arbitrary constant curvature, and they are conformally related to the matching of different solutions of constant curvature by means of an improper conformal transformation. The wormholes can be con...

Exact Spherically Symmetric Solutions in Massive Gravity

A phase of massive gravity free from pathologies can be obtained by coupling the metric to an additional spin-two field. We study the gravitational field produced by a static spherically symmetric body, by finding the exact solution that generalizes the Schwarzschild metric to the case of massive gravity. Besides the usual 1/r term, the main effects of the new spin-two field are a shift of the ...

Generating spherically symmetric static perfect fluid solutions

By a choice of new variables the pressure isotropy condition for spherically symmetric static perfect fluid spacetimes can be made a quadratic algebraic equation in one of the two functions appearing in it. Using the other variable as a generating function, the pressure and the density of the fluid can be expressed algebraically by the function and its derivatives. One of the functions in the m...

Non-Static Spherically Symmetric Perfect Fluid Solutions

We investigate solutions of Einstein field equations for the nonstatic spherically symmetric perfect fluid case using different equations of state. The properties of an exact spherically symmetric perfect fluid solutions are obtained which contain shear. We obtain three different solutions out of these one turns out to be an incoherent dust solution and the other two are stiff matter solutions.
