Delivery of complex organic molecules to the system of Jupiter

T. Benest Couzinou, A. Amsler Moulanier, O. Mousis

Complex organic molecules are key markers of molecular diversity, and their formation conditions in protoplanetary disks remain an active area of research. These molecules have bee…

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…

On the Divergent Evolution of Io and Europa as Primordial Ocean Worlds

Yannis Bennacer, Olivier Mousis, Vincent Hue

The Galilean moons exhibit a decrease in bulk density with distance from Jupiter, which may reflect differences in evolutionary paths and water loss. Early in its history, Jupiter…

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…

Noble gas depletion on Titan: Clathrate sequestration during the open ocean phase

Alizée Amsler Moulanier, Olivier Mousis, Alexis Bouquet +1

A plausible explanation for the absence of primordial argon, krypton, and xenon in Titan's current atmosphere is that these gases were sequestered in clathrate hydrates during Tita…

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…
