The impact of lake shape and size on lake breezes and air-lake exchanges on Titan

Audrey Chatain, Scot C. R. Rafkin, Alejandro Soto +5

Titan, the largest moon of Saturn, has many lakes on its surface, formed mainly of liquid methane. Like water lakes on Earth, these methane lakes on Titan likely profoundly affect…

Remarks on compressible convection in Super-Earths

Yanick Ricard, Thierry Alboussière

The radial density of planets increases with depth due to compressibility, leading to impacts on their convective dynamics. To account for these effects, including the presence of…

How the origin of stars in the Galaxy impacts the composition of planetary building blocks

N. Cabral, A. Guilbert-Lepoutre, B. Bitsch +2

Context. Our Galaxy is composed of different stellar populations with varying chemical abundances, which are thought to imprint the composition of planet building blocks (PBBs). As…

On averaging eccentric orbits: Implications for the long-term thermal evolution of comets

Anastasios Gkotsinas, Aurélie Guilbert-Lepoutre, Sean N. Raymond

One of the common approximations in long-term evolution studies of small bodies is the use of circular orbits averaging the actual eccentric ones, facilitating the coupling of proc…

The gateway from Centaurs to Jupiter-family Comets: thermal and dynamical evolution

Aurélie Guilbert-Lepoutre, Anastasios Gkotsinas, Sean N. Raymond +1

It was recently proposed that there exists a "gateway" in the orbital parameter space through which Centaurs transition to Jupiter-family Comets (JFCs). Further studies have implie…

Evolution of pits at the surface of 67P/Churyumov-Gerasimenko

Selma Benseguane, Aurélie Guilbert-Lepoutre, Jérémie Lasue +6

The observation of pits at the surface of comets offers the opportunity to take a glimpse into the properties and the mechanisms that shape a nucleus through cometary activity. If…

On the Slow Drift of Solstices: Milankovic Cycles and Mean Global Temperature

F. Lopes, V. Courtillot, D. Gibert +1

The Earth's revolution is modified by changes in inclination of its rotation axis. Despite the fact that the gravity field is central, the Earth's trajectory is not closed and the…

Martian meteorites reflectance and implications for rover missions

Lucia Mandon, Pierre Beck, Cathy Quantin-Nataf +7

In the next decade, two rovers will characterize in situ the mineralogy of rocks on Mars, using for the first time near-infrared reflectance spectrometers: SuperCam onboard the Mar…

Thermal processing of Jupiter Family Comets during their chaotic orbital evolution

Anastasios Gkotsinas, Aurélie Guilbert-Lepoutre, Sean N. Raymond +1

Evidence for cometary activity beyond Jupiter and Saturn's orbits -- such as that observed for Centaurs and long period comets -- suggests that the thermal processing of comet nucl…

A molecular wind blows out of the Kuiper belt

Quentin Kral, J. E. Pringle, Aurélie Guilbert-Lepoutre +9

Gas has been detected in many exoplanetary systems (10 Myr), thought to be released in the destruction of volatile-rich planetesimals orbiting in exo-Kuiper belts. In this lette…

Metallization of Shock-Compressed Liquid Ammonia

A. Ravasio, M. Bethkenhagen, J. -A. Hernandez +8

Ammonia is predicted to be one of the major components in the depths of the ice giant planets Uranus and Neptune. Their dynamics, evolution, and interior structure are insufficient…

Benchmarking the ab initio hydrogen equations of state for the interior structure of Jupiter

S. Mazevet, A. Licari, F. Soubiran

As Juno is presently measuring Jupiter's gravitational moments to unprecedented accuracy, models for the interior structure of the planet are putted to the test. While equations of…

Voluminous silica precipitated from martian waters during late-stage aqueous alteration

L. Pan, J. Carter, C. Quantin-Nataf +6

Mars' transition from an early "warm and wet" to the "cold and dry" environment left fingerprints on the geological record of fluvial activity on Mars. The morphological and minera…
