چکیده

This work discusses about the existence of compact star model in context [Formula: see text] gravity with as Ricci scalar and trace energy–momentum tensor text]. The has been developed by considering spherically symmetric spacetime consisting isotropic fluid be coupling parameter. corresponding field equations are solved choosing well-known Finch–Skea ansatz [M. R. Finch J. E. F. Skea, A realistic stellar based on an Duorah Ray, Class. Quantum Gravity 6(4) (1989) 467–476]. For continuity, we elaborate boundary conditions exterior region Schwarzschild metric. unknown constants appearing solution evaluated for PSR J 1614-2230 different values constant. physical properties model, e.g. matter density, pressure, stability, etc. have discussed both analytically graphically. analysis showed that geometry compatible each other well is stable equilibrium modified gravity.

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...

Gravity, Turbulence, and Star Formation

The azimuthal power spectra of optical emission from star formation and dust in spiral galaxies resembles the azimuthal power spectra of HI emission from the LMC. These and other power spectra of whole galaxies all resemble that of velocity in incompressible Kolmogorov turbulence. The reasons for this are unknown but it could be simply that star and cloud formation are the result of a mixture o...
