Interiors of Terrestrial Planets in Metric-Affine Gravity

Aleksander Kozak et al.

Summary: Using a semiempirical approach, this study demonstrates that modified gravity has an impact on the internal properties of terrestrial planets, including their core, mantle, and core-mantle boundary. These findings are also applied to modeling a two-layer exoplanet under Palatini f(R) gravity.

White dwarf stars in modified gravity

Aneta Wojnar

Summary: Modified gravity framework may provide alternative explanations to white dwarfs' cooling processes, age determination, and Chandrasekhar mass limits. Additionally, the Chandrasekhar limit has been obtained from Palatini f(Script capital R) gravity introduced by a simple Lane-Emden model.

Modified gravity in the interior of population II stars

Shaswata Chowdhury et al.

Summary: The study investigates the effects of modified gravity beyond Horndeski theory in the interior of a population II star, finding that reduced gravity may result in decreased luminosity and increased radius of the star, but some effects are reversed near the core. The model provides a constraint on the modified gravity parameter within its limitations.

Jupiter and jovian exoplanets in Palatini f ((R)over-bar) gravity

Aneta Wojnar

Summary: Palatini f((R) over bar) gravity has been shown to impact certain parts of substellar evolution, such as fragmentation of a gaseous cloud and cooling of Jupiter-like planets. Simple models describing these processes demonstrate differences in opacity mass limit and cooling time of jovian planets in modified gravity.

Metric-affine gravity effects on terrestrial exoplanet profiles

Aleksander Kozak et al.

Summary: The mass-radius relations of homogeneous cold spheres made from six common solid materials found in terrestrial planets are discussed, along with an additional degeneracy in (exo)planet profiles and their properties derived from findings in Palatini f(R) gravity framework. Furthermore, a new test of gravity is proposed where seismic data from earthquakes and marsquakes can be used to test and constrain gravity models.

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

Maria Benito et al.

Summary: The study presents an analytical model for the evolution of brown dwarfs in quadratic Palatini f(R) gravity, improving on previous studies by incorporating a more realistic description of the partially degenerate state and considering the hydrogen metallic-molecular phase transition. The revised cooling process for substellar objects is also addressed in this improved model.
