Contrasting C/O ratios in Uranus and Neptune from disequilibrium chemistry: A clue to distinct evolutionary pathways?
T. Briand, V. Hue, O. Mousis +4
The formation of Uranus and Neptune remains poorly constrained largely due to uncertain deep elemental abundances. Carbon monoxide (CO), a disequilibrium species in the upper tropo…
Formation and Survival of Complex Organic Molecules in the Jovian Circumplanetary Disk
Olivier Mousis, Clément Petetin, Tom Benest Couzinou +2
Europa, Ganymede, and Callisto are key targets in the search for habitability due to the potential presence of subsurface oceans. Detecting complex organic molecules (COMs), essent…
Conditions for accretion favoring an unmelted Callisto and a differentiated Ganymede
Yannis Bennacer, Olivier Mousis, Marc Monnereau +2
Analysis of Callisto's moments of inertia, derived from Galileo's gravity data, suggests that its structure is not fully differentiated. This possibly undifferentiated state contra…
Primordial Origin of Methane on Eris and Makemake Supported by D/H Ratios
Olivier Mousis, Aaron Werlen, Tom Benest Couzinou +1
Deuterium, a heavy isotope of hydrogen, is a key tracer of the formation of the Solar System. Recent JWST observations have expanded the dataset of D/H ratios in methane on the KBO…
Understanding the formation of Saturn's regular moons in the context of giant planet moons formation scenarios
Michel Blanc, Aurélien Crida, Yuhito Shibaike +7
This article explores the different formation scenarios of the Kronian moons system in the context of a highly dissipative Saturn, with the objective of identifying the most likely…
Journey of complex organic molecules: Formation and transport in protoplanetary disks
T. Benest Couzinou, O. Mousis, G. Danger +3
Complex organic molecules serve as indicators of molecular diversity. Their detection on comets, planets, and moons has prompted inquiries into their origins, particularly the cond…
Impact of Jupiter's heating and self-shadowing on the Jovian circumplanetary disk structure
Antoine Schneeberger, Olivier Mousis
Deciphering the structure of the circumplanetary disk that surrounded Jupiter at the end of its formation is key to understanding how the Galilean moons formed. Three-dimensional h…
Insights on the Formation Conditions of Uranus and Neptune from their Deep Elemental Compositions
Olivier Mousis, Antoine Schneeberger, Thibault Cavalié +6
This study, placed in the context of the preparation for the Uranus Orbiter Probe mission, aims to predict the bulk volatile compositions of Uranus and Neptune. Using a protoplanet…
Recipes for forming a carbon-rich giant planet
Olivier Mousis, Thibault Cavalié, Jonathan I. Lunine +9
The exploration of carbon-to-oxygen ratios has yielded intriguing insights into the composition of close-in giant exoplanets, giving rise to a distinct classification: carbon-rich…
Formation of the Trappist-1 system in a dry protoplanetary disk
Antoine Schneeberger, Olivier Mousis, Magali Deleuil +1
A key feature of the Trappist-1 system is its monotonic decrease in bulk density with growing distance from the central star, which indicates an ice mass fraction that is zero in t…
Early stages of Galilean moon formation in a water-depleted environment
Olivier Mousis, Antoine Schneeberger, Jonathan I. Lunine +3
A key feature of the Galilean satellite system is its monotonic decrease in bulk density with distance from Jupiter, indicating an ice mass fraction that is zero in the innermost m…
Evolution of the reservoirs of volatiles in the protosolar nebula
Antoine Schneeberger, Olivier Mousis, Artyom Aguichine +1
The supersolar abundances of volatiles observed in giant planets suggest that a compositional gradient was present at the time of their formation in the protosolar nebula. To expla…
Moonraker -- Enceladus Multiple Flyby Mission
O. Mousis, A. Bouquet, Y. Langevin +50
Enceladus, an icy moon of Saturn, possesses an internal water ocean and jets expelling ocean material into space. Cassini investigations indicated that the subsurface ocean could b…
K-Stacker, an algorithm to hack the orbital parameters of planets hidden in high-contrast imaging. First applications to VLT SPHERE multi-epoch observations
H. Le Coroller, M. Nowak, P. Delorme +40
Recent high-contrast imaging surveys, looking for planets in young, nearby systems showed evidence of a small number of giant planets at relatively large separation beyond typicall…
