Cooling process of brown dwarfs in Palatini f(R) gravity

María Benito, Aneta Wojnar

We present an analytical model for the evolution of brown dwarfs in quadratic Palatini f(R) gravity. We improve previous studies by adopting a more realistic description of the par…

Lithium abundance is a gravitational model dependent quantity

Aneta Wojnar

The dependence of lithium abundance on modified gravity in low-mass stellar objects is demonstrated. This may introduce an additional uncertainty to age determination techniques of…

Early evolutionary tracks of low-mass stellar objects in modified gravity

Aneta Wojnar

Using a simple model of low-mass stellar objects we have shown modified gravity impact on their early evolution, such as Hayashi tracks, radiative core development, effective tempe…

Stability of polytropic stars in Palatini gravity

Aneta Wojnar

We will briefly discuss the necessary conditions for stability of polytropies in Palatini gravity and the differences with the General Relativity ones.

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…
