Palatini gravity in the solar system: post-Newtonian equations of motion and complete PPN parameters
Júnior D. Toniato, Davi C. Rodrigues, Aneta Wojnar
We perform a post-Newtonian (PN) solar system analysis for Palatini theories considering finite volume non-spherical planets and with emphasis to functions that are a…
Stellar structure models in modified theories of gravity: lessons and challenges
Gonzalo J. Olmo, Diego Rubiera-Garcia, Aneta Wojnar
The understanding of stellar structure represents the crossroads of our theories of the nuclear force and the gravitational interaction under the most extreme conditions observably…
Minimum main sequence mass in quadratic Palatini gravity
Gonzalo J. Olmo, Diego Rubiera-Garcia, Aneta Wojnar
General Relativity yields an analytical prediction of a minimum required mass of roughly for a star to stably burn sufficient hydrogen to fully compensat…
Primordial density fluctuations generated by wormholes
Marek Rogatko, Aneta Wojnar, Bartlomiej KIczek
We studied the influence of a wormhole existing in the expanding Universe and passing through the horizon volume on the energy density of the Universe. The two-point correlation fu…
On the existence of static spherically-symmetric objects in action-dependent Lagrangian theories
Julio C. Fabris, Hermano Velten, Aneta Wojnar
We study static symmetric solutions in the context of a gravitational theory based on a action-dependent Lagrangian. Such theory has been designed as a setup to implement dissipati…
The Palatini star: exact solutions of the modified Lane-Emden equation
A. Sergyeyev, A. Wojnar
Two exact solutions for and of the Palatini-modified Lane-Emden equation are found. We have employed these solutions to describe a Palatini-Newtonian neutron star and c…
