Non-homogeneous exoplanets in metric-affine gravity
Aleksander Kozak, Aneta Wojnar
Abstract
The improved description of the planets’ interior is provided. We examine the modified gravity effects on the Earth-like planets composed of the iron core and silicate mantle. We confirm that the mass–radius relations as well as density profiles differ with respect to the commonly adopted Newtonian models.
