Giant planet formation in Palatini gravity

Abstract

Some parts of the accretion model of the jovian planets' formation are studied in the context of Palatini gravity. We mainly focus on the critical core mass, that is, a mass for which there is no hydrostatic equilibrium solution for the planet's envelope, which is a starting point of the runaway accretion. We also discuss the conditions needed to be satisfied by a planet such that it can posses a massive gaseous envelope around a solid core.
