[astro-ph.EP]. Empirical relations and planet formation simulations suggest an upper mass limit for rocky planets of ∼10M⊕, as cores above this will almost certainly undergo runaway gas accretion.

Homogeneous Accretion Of The Earth In The Inner Solar System
Meteorites are classified as either non-carbonaceous- (NC) or carbonaceous (CC), representing bodies that likely formed in the inner- or outer solar system, respectively. Despite its location in the inner solar […]

Estimation Of The Tidal Heating In The TRAPPIST-1 Planets. Influence Of The Internal Structure
With the arrival of JWST observations of the TRAPPIST-1 planets, it is timely to reassess the contribution of tidal heating to their heat budget. JWST thermal phase curves could reveal […]

Formation Of Cold Giant Planets Around Late M Dwarfs Via Core Accretion And The Fate Of Inner Rocky Worlds
Modeling the formation of cold giant planets around M dwarfs is difficult because their disks may not contain enough solids to form massive cores and because forming giants are expected […]

Uranus And Neptune Might Be Rock Giants
The planets in the Solar System are typically divided into three categories based on their composition: the four terrestrial rocky planets (Mercury, Venus, Earth and Mars), followed by the two […]
