Probing clumpy stellar winds with a neutron-star
R. Walter, J. Zurita-Heras, J. -C. Leyder
INTEGRAL tripled the number of super-giant high-mass X-ray binaries (sgHMXB) known in the Galaxy by revealing absorbed and fast transient (SFXT) systems. Quantitative constraints o…
Hard X-ray emission from Eta Carinae
Jean-Christophe Leyder, Roland Walter, Gregor Rauw
Context : If relativistic particle acceleration takes place in colliding-wind binaries, hard X-rays and gamma-rays are expected through inverse Compton emission, but to date these…
Hard X-ray flares in IGR J08408-4503 unveil clumpy stellar winds
Jean-Christophe Leyder, Roland Walter, Michalis Lazos +2
Context : A 1000-s flare from a new hard X-ray transient, IGR J08408-4503, was observed by INTEGRAL on May 15, 2006 during the real-time routine monitoring of IBIS/ISGRI images per…
Probing clumpy stellar winds with a neutron star
R. Walter, J. Zurita Heras
INTEGRAL, the European Space Agency's gamma-ray observatory, tripled the number of super-giant high-mass X-ray binaries (sgHMXB) known in the Galaxy by revealing absorbed and fast…
A search for solar-like oscillations in the Am star HD 209625
F. Carrier, P. Eggenberger, J. C. Leyder +2
The goal is to test the structure of hot metallic stars, and in particular the structure of a near-surface convection zone using asteroseismic measurements. Indeed, stellar models…
