Coupling between corotation and Lindblad resonances in the elliptic planar three-body problem
Maryame El Moutamid, Bruno Sicardy, Stéfan Renner
We investigate the dynamics of two satellites with masses and orbiting a massive central planet in a common plane, near a first order mean motion resonance +1: (…
Unexpected D-type Interlopers in the Inner Main Belt
Francesca E. DeMeo, Richard P. Binzel, Benoit Carry +2
Very red featureless asteroids (spectroscopic D-types) are expected to have formed in the outer solar system far from the sun. They comprise the majority of asteroids in the Jupite…
Spin-orbit coupling and chaotic rotation for coorbital bodies in quasi-circular orbits
Alexandre C. M. Correia, Philippe Robutel
Coorbital bodies are observed around the Sun sharing their orbits with the planets, but also in some pairs of satellites around Saturn. The existence of coorbital planets around ot…
Impact of the frequency dependence of tidal Q on the evolution of planetary systems
P. Auclair-Desrotour, C. Le Poncin-Lafitte, S. Mathis
Context. Tidal dissipation in planets and in stars is one of the key physical mechanisms that drive the evolution of planetary systems. Aims. Tidal dissipation properties are intri…
Orbital and physical properties of planets and their hosts: new insights on planet formation and evolution
V. Zh. Adibekyan, P. Figueira, N. C. Santos +7
We explore the relations between physical and orbital properties of planets and properties of their host stars to identify the main observable signatures of the formation and evolu…
FIRST, a fibered aperture masking instrument II. Spectroscopy of the Capella binary system at the diffraction limit
E. Huby, G. Duchêne, F. Marchis +7
FIRST is a prototype instrument built to demonstrate the capabilities of the pupil remapping technique, using single-mode fibers and working at visible wavelengths. We report on ob…
Characteristics and Large Bulk Density of the C-type Main-Belt Triple Asteroid (93) Minerva
F. Marchis, F. Vachier, J. Ďurech +11
From a set of adaptive optics (AO) observations collected with the W.M. Keck telescope between August and September 2009, we derived the orbital parameters of the most recently dis…
Anisotropic q-Gaussian velocity distributions in LambdaCDM halos
Leandro J. Beraldo e Silva, Gary A. Mamon, Manuel Duarte +3
The velocity distribution function (VDF) of dark matter (DM) halos in CDM dissipationless cosmological simulations, which must be non-separable in its radial and tangential comp…
A semi-empirical stability criterion for real planetary systems
C. A. Giuppone, M. H. M. Morais, A. C. M. Correia
We test a crossing orbit stability criterion for eccentric planetary systems, based on Wisdom's criterion of first order mean motion resonance overlap (Wisdom, 1980). We show that…
17P/Holmes: Contrast in activity between before and after the 2007 outburst
Masateru Ishiguro, Yoonyoung Kim, Dhanraj S. Warjurkar +9
A Jupiter-family comet, 17P/Holmes, underwent outbursts in 1892 and 2007. In particular, the 2007 outburst is known as the greatest outburst over the past century. However, little…
739 observed NEAs and new 2-4m survey statistics within the EURONEAR network
O. Vaduvescu, M. Birlan, A. Tudorica +36
We report follow-up observations of 477 program Near-Earth Asteroids (NEAs) using nine telescopes of the EURONEAR network having apertures between 0.3 and 4.2 m. Adding these NEAs…
Quasi-periodic Almost-collision Orbits in the Spatial Three-Body Problem
Lei Zhao
In a system of particles, quasi-periodic almost-collision orbits are collisionless orbits along which two bodies become arbitrarily close to each other -- the lower limit of their…
Detecting filamentary pattern in the cosmic web: a catalogue of filaments for the SDSS
E. Tempel, R. S. Stoica, V. J. Martinez +3
The main feature of the spatial large-scale galaxy distribution is its intricate network of galaxy filaments. This network is spanned by the galaxy locations that can be interprete…
The taxonomic distribution of asteroids from multi-filter all-sky photometric surveys
Francesca DeMeo, Benoit Carry
The distribution of asteroids across the Main Belt has been studied for decades to understand the compositional distribution and what that tells us about the formation and evolutio…
On the extension of the Laplace-Lagrange secular theory to order two in the masses for extrasolar systems
Anne-Sophie Libert, Marco Sansottera
We study the secular evolution of several exoplanetary systems by extending the Laplace-Lagrange theory to order two in the masses. Using an expansion of the Hamiltonian in the Poi…
Evidence of a metal-rich surface for the asteroid (16) Psyche from interferometric observations in the thermal infrared
Alexis Matter, Marco Delbo, Benoit Carry +1
We describe the first determination of thermal properties and size of the M-type asteroid (16) Psyche from interferometric observations obtained with the Mid-Infrared Interferometr…
Survey of cometary CO2, CO, and particulate emissions using the Spitzer Space Telescope: Smog check for comets
William T. Reach, Michael S. Kelley, Jeremie Vaubaillon
We surveyed 23 comets using the Infrared Array Camera on the Spitzer Space Telescope in wide filters centered at 3.6 and 4.5 microns. Emission in the 3.6 micron filter arises from…
The HARPS search for southern extra-solar planets. XXXIV. A planetary system around the nearby M dwarf GJ163, with a super-Earth possibly in the habitable zone
X. Bonfils, G. Lo Curto, A. C. M. Correia +19
The meter-per-second precision achieved by today velocimeters enables the search for 1-10 M_Earth planets in the habitable zone of cool stars. This paper reports on the detection o…
High Order Three Part Split Symplectic Integration Schemes
Enrico Gerlach, Siegfried Eggl, Charalampos Skokos +2
Symplectic integration methods based on operator splitting are well established in many branches of science. For Hamiltonian systems which split in more than two parts, symplectic…
Use of MESSENGER radioscience data to improve planetary ephemeris and to test general relativity
Ashok Verma, Agnes Fienga, Jacques Laskar +2
The current knowledge of Mercury orbit has mainly been gained by direct radar ranging obtained from the 60s to 1998 and by five Mercury flybys made by Mariner 10 in the 70s, and ME…
Highly inclined and eccentric massive planets I: Planet-disc interactions
