Theory of the rotation of Janus and Epimetheus
B. Noyelles
The Saturnian coorbital satellites Janus and Epimetheus present a unique dynamical configuration in the Solar System, because of high-amplitude horseshoe orbits, due to a mass rati…
Physical Properties of (2) Pallas
Benoit Carry, Christophe Dumas, Mikko Kaasalainen +8
We acquired and analyzed adaptive-optics imaging observations of asteroid (2) Pallas from Keck II and the Very Large Telescope taken during four Pallas oppositions between 2003 and…
Neptune Trojans and Plutinos: colors, sizes, dynamics, and their possible collisions
A. J. C. Almeida, N. Peixinho, A. C. M. Correia
Neptune Trojans and Plutinos are two subpopulations of trans-Neptunian objects located in the 1:1 and the 3:2 mean motion resonances with Neptune, respectively, and therefore prote…
A collisionless scenario for Uranus tilting
Gwenaël Boué, Jacques Laskar
The origin of the high inclination of Uranus' spin-axis (Uranus' obliquity) is one of the great unanswered questions about the Solar system. Giant planets are believed to form with…
Transit timing analysis of CoRoT-1b
Sz. Csizmadia, S. Renner, P. Barge +33
CoRoT, the pioneer space-based transit search, steadily provides thousands of high-precision light curves with continuous time sampling over periods of up to 5 months. The transits…
Dynamical stability analysis of the HD202206 system and constraints to the planetary orbits
J. Couetdic, J. Laskar, A. C. M. Correia +2
Long-term precise Doppler measurements with the CORALIE spectrograph revealed the presence of two massive companions to the solar-type star HD202206. Although the three-body fit of…
On invariant sets in Lagrangian graphs
Xiaojun Cui, Lei Zhao
In this exposition, we show that a Hamiltonian is always constant on a compact invariant connected subset which lies in a Lagrangian graph provided that the Hamiltonian and the gra…
High inclination orbits in the secular quadrupolar three-body problem
Francois Farago, Jacques Laskar
The Lidov-Kozai mechanism allows a body to periodically exchange its eccentricity with inclination. It was first discussed in the framework of the quadrupolar secular restricted th…
A local prescription for the softening length in self-gravitating gaseous discs
Jean-Marc Huré, Arnaud Pierens
In 2D-simulations of self-gravitating gaseous discs, the potential is often computed in the framework of "softened gravity" initially designed for N-body codes. In this special con…
Speed limit on Neptune migration imposed by Saturn tilting
Gwenaël Boué, Jacques Laskar, Petr Kuchynka
In this Letter, we give new constraints on planet migration. They were obtained under the assumption that Saturn's current obliquity is due to a capture in resonance with Neptune's…
Eclipsing Binary Trojan Asteroid Patroclus: Thermal Inertia from Spitzer Observations
Michael Mueller, Franck Marchis, Joshua P. Emery +5
We present mid-infrared (8-33 micron) observations of the binary L5-Trojan system (617) Patroclus-Menoetius before, during, and after two shadowing events, using the Infrared Spect…
Long-term evolution of the spin of Mercury I. Effect of the obliquity and core-mantle friction
A. C. M. Correia, J. Laskar
The present obliquity of Mercury is very low (less than 0.1 degree), which led previous studies to always adopt a nearly zero obliquity during the planet's past evolution. However,…
Rate and nature of false positives in the CoRoT exoplanet search
J. M. Almenara, H. J. Deeg
Context. The CoRoT satellite searches for planets by applying the transit method, monitoring up to 12 000 stars in the galactic plane for 150 days in each observation run. This sea…
Planetary transit candidates in COROT-IRa01 field
S. Carpano, J. Cabrera, R. Alonso +35
Context: CoRoT is a pioneering space mission devoted to the analysis of stellar variability and the photometric detection of extrasolar planets. Aims: We present the list of planet…
The Large Quasar Reference Frame (LQRF) - an optical representation of the ICRS
A. H. Andrei, J. Souchay, N. Zacharias +9
The large number and all-sky distribution of quasars from different surveys, along with their presence in large, deep astrometric catalogs,enables the building of an optical materi…
Order statistics and heavy-tail distributions for planetary perturbations on Oort cloud comets
R. S. Stoica, S. Liu, Yu. Davydov +3
This paper tackles important aspects of comets dynamics from a statistical point of view. Existing methodology uses numerical integration for computing planetary perturbations for…
A multiwavelength study of Swift GRB 060111B constraining the origin of its prompt optical emission
G. Stratta, A. Pozanenko, J-L. Atteia +18
In this work, we present the results obtained from a multi-wavelength campaign, as well as from the public Swift/BAT, XRT, and UVOT data of GRB 060111B for which a bright optical e…
EURONEAR - Data Mining of Asteroids and Near Earth Asteroids
O. Vaduvescu, L. Curelaru, M. Birlan +4
Besides new observations, mining old photographic plates and CCD image archives represents an opportunity to recover and secure newly discovered asteroids, also to improve the orbi…
Gravity tests with INPOP planetary ephemerides
A. Fienga, J. Laskar, P. Kuchynka +3
In this paper, we present several gravity tests made in using the last INPOP08 planetary ephemerides. We first propose two methods to estimate the PPN parameter and its correla…
Kinematic deprojection and mass inversion of spherical systems of known velocity anisotropy
Gary A. Mamon, Gwenael Boué
Traditionally, the mass / velocity anisotropy degeneracy (MAD) inherent in the spherical, stationary, non-streaming Jeans equation has been handled by assuming a mass profile and f…
INPOP08, a 4-D planetary ephemeris: From asteroid and time-scale computations to ESA Mars Express and Venus Express contributions
A. Fienga, J. Laskar, T. Morley +6
The latest version of the planetary ephemerides developed at the Paris Observatory and at the Besancon Observatory is presented here. INPOP08 is a 4-dimension ephemeris since it pr…
A Giant Crater on 90 Antiope?
P. Descamps, F. Marchis, T. Michalowski +11
Mutual event observations between the two components of 90 Antiope were carried out in 2007-2008. The pole position was refined to lambda0 = 199.5+/-0.5 eg and beta0 = 39.8+/-5 deg…
Un théorème sur les actions de groupes de dimension infinie
Jacques Féjoz, Mauricio Garay
We give an infinitesimal criterion, in the analytic setting, for a vector space to be locally homogeneous under some group action. Our approach differs from those which resort to a…
