Shape modeling technique KOALA validated by ESA Rosetta at (21) Lutetia
B. Carry, M. Kaasalainen, W. J. Merline +12
We present a comparison of our results from ground-based observations of asteroid (21) Lutetia with imaging data acquired during the flyby of the asteroid by the ESA Rosetta missio…
The population of natural Earth satellites
Mikael Granvik, Jeremie Vaubaillon, Robert Jedicke
We have for the first time calculated the population characteristics of the Earth's irregular natural satellites (NES) that are temporarily captured from the near-Earth-object (NEO…
Lagrangian for the Convection-Diffusion Equation
Jacky Cresson, Isabelle Greff, Pierre Inizan
Using the asymmetric fractional calculus of variations, we derive a fractional Lagrangian variational formulation of the convection-diffusion equation in the special case of consta…
A pre-Caloris synchronous rotation for Mercury
Mark A. Wieczorek, Alexandre C. M. Correia, Mathieu Le Feuvre +2
The planet Mercury is locked in a spin-orbit resonance where it rotates three times about its spin axis for every two orbits about the Sun. The current explanation for this unique…
Non integrability of the n body problem with non zero angular momentum
Thierry Combot
We prove an integrability criterion and a partial integrability criterion for homogeneous potentials of degree -1 which are invariant by rotation. We then apply it to the proof of…
Pumping the eccentricity of exoplanets by tidal effect
Alexandre C. M. Correia, Gwenaël Boué, Jacques Laskar
Planets close to their host stars are believed to undergo significant tidal interactions, leading to a progressive damping of the orbital eccentricity. Here we show that, when the…
Behavior of nearby synchronous rotation of a Poincaré-Hough satellite at low eccentricity
Benoît Noyelles
This paper presents a study of the Poincaré-Hough model of rotation of the synchronous natural satellites, in which these bodies are assumed to be composed of a rigid mantle and a…
Testing Gravitation in the Solar System with Radio Science experiments
A. Hees, P. Wolf, B. Lamine +5
The laws of gravitation have been tested for a long time with steadily improving precision, leading at some moment of time to paradigmatic evolutions. Pursuing this continual effor…
The Lagrange reduction of the N-body problem, a survey
Alain Chenciner
In his fondamental "Essay on the 3-body problem", Lagrange, well before Jacobi's "reduction of the node", carries out the first complete reduction of symetries. Discovering the so-…
Third order integrability conditions for homogeneous potentials of degree -1
Thierry Combot, Christoph Koutschan
We prove an integrability criterion of order 3 for a homogeneous potential of degree -1 in the plane. Still, this criterion depends on some integer and it is impossible to apply it…
Influence of the coorbital resonance on the rotation of the Trojan satellites of Saturn
Philippe Robutel, Nicolas Rambaux, Maryame El Moutamid
The Cassini spacecraft collects high resolution images of the saturnian satellites and reveals the surface of these new worlds. The shape and rotation of the satellites can be dete…
Chaotic diffusion of the Vesta family induced by close encounters with massive asteroids
J. -B. Delisle, J. Laskar
We numerically estimate the semi-major axis chaotic diffusion of the Vesta family asteroids induced by close encounters with 11 massive main belt asteroids : (1) Ceres, (2) Pallas,…
Tidal dissipation in multi-planet systems and constraints to orbit-fitting
Jacques Laskar, Gwenaël Boué, Alexandre C. M. Correia
We present here in full details the linear secular theory with tidal damping that was used to constraint the fit of the HD10180 planetary system in (Lovis et al. 2011). The theory…
Planetary transit candidates in the CoRoT LRa01 field
L. Carone, D. Gandolfi, J. Cabrera +70
Context: CoRoT is a pioneering space mission whose primary goals are stellar seismology and extrasolar planets search. Its surveys of large stellar fields generate numerous planeta…
Interpretation of (596) Scheila's Triple Dust Tails
Masateru Ishiguro, Hidekazu Hanayama, Sunao Hasegawa +16
Strange-looking dust cloud around asteroid (596) Scheila was discovered on 2010 December 11.44-11.47. Unlike normal cometary tails, it consisted of three tails and faded within two…
GRB 110205A: Anatomy of a long gamma-ray burst
B. Gendre, J. L. Atteia, M. Boër +8
The Swift burst GRB 110205A was a very bright burst visible in the Northern hemisphere. GRB 110205A was intrinsically long and very energetic and it occurred in a low-density inter…
The rotation of Mimas
Benoît Noyelles, Özgür Karatekin, Nicolas Rambaux
The Cassini mission in the Saturnian system is an outstanding opportunity to improve our knowledge of the satellites of Saturn. The data obtained thanks to this mission must be con…
Accretion of Saturn's mid-sized moons during the viscous spreading of young massive rings: solving the paradox of silicate-poor rings versus silicate-rich moons
Sébastien Charnoz, Aurélien Crida, Julie C. Castillo-Rogez +7
The origin of Saturn's inner mid-sized moons (Mimas, Enceladus, Tethys, Dione and Rhea) and Saturn's rings is debated. Charnoz et al. (2010) introduced the idea that the smallest i…
Orbital migration induced by anisotropic evaporation. Can hot Jupiters form hot Neptunes ?
Gwenaël Boué, Pedro Figueira, Alexandre C. M. Correia +1
Short period planets are subject to intense energetic irradiations from their stars. It has been shown that this can lead to significant atmospheric mass-loss and create smaller ma…
Integral-field spectroscopy of (90482) Orcus-Vanth
B. Carry, D. Hestroffer, F. DeMeo +8
Aims. We seek to constrain the surface composition of the Trans-Neptunian Object (90482) Orcus and its small satellite Vanth, as well as their mass and density. Methods. We acquire…
