Equilibrium figure of Haumea and possible detection by stellar occultation
C. Staelen, N. Rambaux, F. Chambat +1
The equilibrium figure of dwarf planet Haumea is studied to determine if the observed shape is compatible with a differentiated hydrostatic body. Three groups of interior models of…
Evolutionary Processes in the Centaur Region
Rosita Kokotanekova, Aurélie Guilbert-Lepoutre, Matthew M. Knight +1
Centaurs populate relatively short-lived and rapidly evolving orbits in the giant-planet region and are believed to be one of the solar system's most complex and diverse population…
Convective regimes of internally heated steady thermal convection of temperature-dependent viscous fluid
Hisashi Okuda, Shin-ichi Takehiro, Stéphane Labrosse
We study dynamical regimes of thermal convection with temperature-dependent viscosity driven by homogeneous internal heating. Two-dimensional steady-state convective solutions with…
Did lunar tides sustain the early Earth's dynamo?
Jérémie Vidal, David Cébron
Geological data show that, early in its history, the Earth had a large-scale magnetic field with an amplitude comparable to the one of the present geomagnetic field. However, its o…
Can the dynamo of spiral-arm galaxies be explained by anisotropic conductivity ?
Paul Gomez, Franck Plunian, Thierry Alboussière
The possibility of generating a magnetic field by dynamo effect with anisotropic electrical conductivity rather than turbulent flow has been demonstrated theoretically (Plunian & A…
Dust evolution by chemisputtering during protostellar formation
Antonin Borderies, Benoît Commerçon, Bernard Bourdon
Dust grains play a crucial role in the modeling of protostellar formation, particularly through their opacity and interaction with the magnetic field. The destruction of dust grain…
On the Optimization of Singular Spectrum Analyses: A Pragmatic Approach
Fernando Lopes, Dominique Gibert, Vincent Courtillot +2
Singular Spectrum Analysis (SSA) occupies a prominent place in the real signal analysis toolkit alongside Fourier and Wavelet analysis. In addition to the two aforementioned analys…
High-temperature dust formation in carbon-rich astrophysical environments
Guy Libourel, Marwane Mokhtari, Vandad-Julien Rohani +7
Condensation processes, which are responsible for the main chemical differences between gas and solids in the Galaxy, are the major mechanisms that control the cycle of dust from e…
Solid-liquid phase change in planetary cores
Ludovic Huguet, Quentin Kriaa, Thierry Alboussière +1
The ubiquitous phenomena of crystallization and melting occur in various geophysical contexts across many spatial and temporal scales. In particular, they take place in the iron co…
On the early thermal processing of planetesimals during and after the giant planet instability
A. Gkotsinas, D. Nesvorny, A. Guilbert-Lepoutre +2
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets' dynamical i…
On the mechanism of thermal self-regulation of trees: a kind of homeothermic observation
Jean-Baptiste Boulé, Jean de Bremond d'Ars, Vincent Courtillot +6
What is certain is that surface temperatures around the globe vary considerably, regardless of the time scales or underlying causes. Since 1850, we have observed an average increas…
Information theory, Signal Analysis and Inverse Problem
Dominique Gibert, Fernando Lopes, Vincent Courtillot +2
This book is intended for teaching Signal Analysis methods and Inverse Problems theory. It is completely open access and will remain free. It is currently illustrated with examples…
Geomagnetic dipole stability and zonal flows controlled by mantle heat flux heterogeneities
Thomas Frasson, Natanaël Schaeffer, Henri-Claude Nataf +1
This work aims at acquiring a more complete understanding of how lateral heterogeneities of the CMB heat flux affect the geodynamo while other relevant parameters are pushed toward…
On the effect of the luni-solar gravitational attraction on trees
Jean-Louis Le Mouël, Dominique Gibert, Jean-Baptiste Boulé +5
In this paper, we revisit old electrical measurements conducted on a poplar tree in 2003 (Gibert et al. 2006), which showed the presence of a diurnal electrical signal, attributed…
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…
Velocity field and cavity dynamics in drop impact experiments
Victor Lherm, Renaud Deguen
Drop impact experiments allow the modelling of a wide variety of natural processes, from raindrop impacts to planetary impact craters. In particular, interpreting the consequences…
On the external forcing of global eruptive activity in the past 300 years
J-L. Le Mouël, D. Gibert, V. Courtillot +11
The decryption of the temporal sequence of volcanic eruptions is a key step in better anticipating future events. Volcanic activity is the result of a complex interaction between i…
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…
Platform for Probing Radiation Transport Properties of Hydrogen at Conditions Found in the Deep Interiors of Red Dwarfs
J. Lütgert, M. Bethkenhagen, B. Bachmann +19
We describe an experimental concept at the National Ignition Facility for specifically tailored spherical implosions to compress hydrogen to extreme densities (up to 800$\tim…
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…
X-ray Thomson scattering spectra from DFT-MD simulations based on a modified Chihara formula
Maximilian Schörner, Mandy Bethkenhagen, Tilo Döppner +3
We study state-of-the-art approaches for calculating x-ray Thomson scattering spectra from density functional theory molecular dynamics (DFT-MD) simulations based on a modified Chi…
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…
