Modelling a Compact Star with Quark Matter
J. E. Horvath, P. H. R. S. Moraes
The detection of an unexpected component in the gravitational wave event GW190814 has puzzled the community of High-Energy astrophysicists, since in the absenc…
Traversable wormholes in the traceless gravity
Parbati Sahoo, P. H. R. S. Moraes, Marcelo M. Lapola +1
We present a traversable wormhole solution using the traceless theory of gravity. In the gravity, the Ricci scalar in the Einstein-Hilbert action is replaced…
Neutron stars in gravity using realistic equations of state in the light of massive pulsars and GW170817
R. Lobato, O. Lourenço, P. H. R. S. Moraes +5
In this work we investigate neutron stars (NS) in gravity for the case , is the Ricci scalar and the trace of the en…
Modeling Dark Matter Halos with Nonlinear Field Theories
R. A. C. Correa, P. H. R. S. Moraes, A. de Souza Dutra +3
In the present work, we adopt a nonlinear scalar field theory coupled to the gravity sector to model galactic dark matter. We found analytical solutions for the scalar field couple…
Stable relativistic polytropic objects with cosmological constant
José D. V. Arbañil, Pedro H. R. S. Moraes
The effects of the cosmological constant on the static equilibrium configurations and stability against small radial perturbations of relativistic polytropic spheres are investigat…
Comment on "Reexamining gravity", Phys. Rev. D 100, 064059 (2019)
Tiberiu Harko, Pedro H. R. S. Moraes
In a recent paper, "Reexamining gravity", by S. B. Fisher and E. D. Carlson, Phys. Rev. D 100, 064059 (2019), the authors claim that for the particular …
