The internal structure of Eris inferred from its spin and orbit evolution

F Nimmo, ME Brown - Science Advances, 2023 - science.org
The large Kuiper Belt object Eris is tidally locked to its small companion Dysnomia. Recently
obtained bounds on the mass of Dysnomia demonstrate that Eris must be unexpectedly …

Thermophysical evolution of planetesimals in the primordial disc

BJR Davidsson - Monthly Notices of the Royal Astronomical …, 2021 - academic.oup.com
The primordial disc of small icy planetesimals, once located at 15–from the Sun, was
disrupted by giant planet migration in the early Solar system. The primordial disc thereby …

Slow evolution of Europa's interior: Metamorphic ocean origin, delayed metallic core formation, and limited seafloor volcanism

KT Trinh, CJ Bierson, JG O'Rourke - Science Advances, 2023 - science.org
Europa's ocean lies atop an interior made of metal and silicates. On the basis of gravity data
from the Galileo mission, many argued that Europa's interior, like Earth, is differentiated into …

The interiors of Uranus and Neptune: current understanding and open questions

R Helled, JJ Fortney - Philosophical Transactions of the …, 2020 - royalsocietypublishing.org
Uranus and Neptune form a distinct class of planets in our Solar System. Given this fact, and
ubiquity of similar-mass planets in other planetary systems, it is essential to understand their …

Carbon-rich icy moons and dwarf planets

B Reynard, C Sotin - Earth and Planetary Science Letters, 2023 - Elsevier
Density and moment of inertia of icy moons and dwarf planets suggest the presence of a low-
density carbonaceous component in their rocky cores. This hypothesis was tested using …
