Symmetric Subresultants and Applications
Cyril Brunie, Philippe Saux Picart
Schur's transforms of a polynomial are used to count its roots in the unit disk. These are generalized them by introducing the sequence of symmetric sub-resultants of two polynomia…
An asymmetry detected in the disk of Kappa CMa with the AMBER/VLTI
Anthony Meilland, Florentin Millour, Philippe Stee +7
Aims. We study the geometry and kinematics of the circumstellar environment of the Be star Kappa CMa in the Br gamma emission line and its nearby continuum. Methods. We use the VLT…
Direct constraint on the distance of y2 Velorum from AMBER/VLTI observations
F. Millour, R. G. Petrov, O. Chesneau +95
In this work, we present the first AMBER observations, of the Wolf-Rayet and O (WR+O) star binary system y2 Velorum. The AMBER instrument was used with the telescopes UT2, UT3, and…
Survey of roughness by stochastic oscillations
Eric Moreau
In this paper, connections between surface roughness and directed polymers in random medium are studied, when the surface is considered as a directed line undergoing stochastic osc…
Near-Infrared interferometry of Eta Carinae with high spatial and spectral resolution using the VLTI and the AMBER instrument
G. Weigelt
We present the first NIR spectro-interferometry of the LBV Eta Carinae. The K band observations were performed with the AMBER instrument of the ESO Very Large Telescope Interferome…
Constraining the wind launching region in Herbig Ae stars: AMBER/VLTI spectroscopy of HD104237
E. Tatulli, A. Isella, A. Natta +3
We investigate the origin of the emission of the Herbig Ae star HD104237 on Astronomical Unit (AU) scales. Using AMBER/VLTI at a spectral resolution R=1500 spatially…
