Variability Analysis: Detection and Classification
Laurent Eyer
Gaia mission will offer an exceptional opportunity to perform variability studies. The data homogeneity, its optimised photometric systems, composed of 11 medium and 4-5 broad band…
First numerical evidence of global Arnold diffusion in quasi--integrable systems
Massimiliano Guzzo, Elena Lega, Claude Froeschle'
We provide numerical evidence of global diffusion occurring in slightly perturbed integrable Hamiltonian systems and symplectic maps. We show that even if a system is sufficiently…
The Sun Asphericities: Astrophysical Relevance
J-P. Rozelot, S. Pireaux, S. Lefebvre +1
Of all the fundamental parameters of the Sun (diameter, mass, temperature...), the gravitational multipole moments (of degree l and order m) that determine the solar moments of ine…
Multifractal concentrations of inertial particles in smooth random flows
Jeremie Bec
Collisionless suspensions of inertial particles (finite-size impurities) are studied in 2D and 3D spatially smooth flows. Tools borrowed from the study of random dynamical systems…
Halpha Kinematics of Tidal Tails in Interacting Systems: Projection Effects and Dark Matter in TDGs
P. Amram, F. Bournaud, P. -A. Duc
Several interacting systems exhibit at the tip of their long tidal tails massive condensations of atomic hydrogen, which may be the progenitors of Tidal Dwarf Galaxies. Because, qu…
Are dust shell models well-suited to explain interferometric data of late-type stars in the near-infrared?
P. Schuller, P. Salomé, G. Perrin +7
Recently available near-infrared interferometric data on late-type stars show a strong increase of diameter for asymptotic giant branch (AGB) stars between the K (2.0 - 2.4 μm) and…
