The exotic chemical composition of the Sagittarius dwarf Spheroidal galaxy
L. Sbordone, P. Bonifacio, R. Buonanno +3
The Sagittarius dwarf Spheroidal galaxy is the nearest neighbor of the Milky Way. Moving along a short period quasi-polar orbit within the Halo, it is being destroyed by the tidal…
NGC5719/13: interacting spirals forming a counter-rotating stellar disc
D. Vergani, A. Pizzella, E. M. Corsini +4
(Context) When a galaxy acquires material from the outside, it is likely that the resulting angular momentum of the accreted material is decoupled from that of the pre-existing gal…
Calibration of the pre-main sequence RS Cha binary system
E. Alecian, M. -J. Goupil, Y. Lebreton +2
Context: The calibration of binary systems with accurately known masses and/or radii provides powerful tools to test stellar structure and evolution theory and to determine the age…
The magnetic field of the pre-main sequence Herbig Ae star HD 190073
C. Catala, E. Alecian, J. -F. Donati +7
The general context of this paper is the study of magnetic fields in the pre-main sequence intermediate mass Herbig Ae/Be stars. Magnetic fields are likely to play an important rol…
Oxygen, Sodium, Magnesium and Aluminium as tracers of the Galactic Bulge Formation
A. Lecureur, V. Hill, M. Zoccali +5
This paper investigates the peculiar behaviour of the light even (alpha-elements) and odd atomic number elements in red giants in the galactic bulge, both in terms of the chemical…
High dynamic range imaging by pupil single-mode filtering and remapping
G. Perrin, S. Lacour, J. Woillez +1
Because of atmospheric turbulence, obtaining high angular resolution images with a high dynamic range is difficult even in the near infrared domain of wavelengths. We propose a nov…
