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…
How dirt cones form on glaciers: field observation, laboratory experiments and modeling
Marceau Hénot, Vincent J. Langlois, Nicolas Plihon +1
Dirt cones are meter-scale structures encountered at the surface of glaciers, which consist of ice cones covered by a thin layer of ashes, sand or gravel, and which form naturally…
A playground for compressible natural convection with a nearly uniform density
Thierry Alboussiere, Jezabel Curbelo, Fabien Dubuffet +2
In the quest to understand the basic universal features of compressible convection, one would like to disentangle genuine consequences of compression from spatial variations of tra…
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…
Diamond formation from hydrocarbon mixtures in planets
Bingqing Cheng, Sebastien Hamel, Mandy Bethkenhagen
Hydrocarbon mixtures are extremely abundant in the Universe, and diamond formation from them can play a crucial role in shaping the interior structure and evolution of planets. Wit…
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…
Fast and Furious dynamo action in the anisotropic dynamo
Franck Plunian, Thierry Alboussière
In the limit of large magnetic Reynolds numbers, it is shown that a smooth differential rotation can lead to fast dynamo action, provided that the electrical conductivity or magnet…
On the Nature and Origin of Atmospheric Annual and Semi-annual Oscillations
V. Courtillot, J-L. Le Mouël, F. Lopes +1
This paper proposes a joint analysis of variations of global sea-level pressure and of Earth's rotation (RP), expressed as the coordinates of the rotation pole and length of day. S…
Fury: an experimental dynamo with anisotropic electrical conductivity
Thierry Alboussière, Franck Plunian, Marc Moulin
We report measurements of dynamo action in a new experimental setup, named Fury, based on the use of an anisotropic electrical conductivity. It consists in a copper rotor rotating…
On the annual and semi-annual components of variations in extent of Arctic and Antarctic sea-ice
F. Lopes, V. Courtillot, D. Gibert +1
The time series of northern hemisphere (NHSI) and southern hemisphere (SHSI) sea-ice extent are submitted to singular spectral analysis (SSA). The components are analyzed with Lapl…
On Sea-Level Change in Coastal Areas
V. Courtillot, JL. Le Mouël, F. Lopes
Variations in sea-level, based on tide gauge data (GSLTG) and on combining tide gauges and satellite data (GSLl) are subjected to singular spectrum analysis (SSA), to determine the…
On two formulations of polar motion and identification of its sources
F. Lopes, V. Courtillot, JL. Le Mouël +1
Differences in interpretation may arise from differences in formulation of the equations of celestial mechanics. This paper focuses on the Liouville system of differential equation…
Same and interconvertible high-pressure ice phases
Aleks Reinhardt, Mandy Bethkenhagen, Federica Coppari +3
Most experimentally known high-pressure ice phases have a body-centred cubic (bcc) oxygen lattice. Our atomistic simulations show that, amongst these bcc ice phases, ices VII, VII'…
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…
