The Palatini formalism of the theory of gravity
J. G. de Lima Júnior, P. H. R. S. Moraes, E. Brito +1
We present the first formulation of the recently proposed theory of gravity within the Palatini formalism, a well-known alternative variational approach wher…

Cosmic slowing down of acceleration with the Chaplygin-Jacobi gas as a dark fluid?
J. A. S. Fortunato, W. S. Hipolito-Ricaldi, N. Videla +1
A particular generalization of the Chaplygin inflationary model, using the formalism of Hamilton-Jacobi and elliptic functions, results in a more general non-linear Chaplygin-type…

Hydrostatic equilibrium configurations of neutron stars in the gravity theory
J. A. S. Fortunato, P. H. R. S. Moraes, E. Brito +2
In the present work, we obtain the hydrostatic equilibrium configurations of neutron stars in the recently proposed theory of gravity, for which is the Ric…
