VESPA: a community-driven Virtual Observatory in Planetary Science
S. Erard, B. Cecconi, P. Le Sidaner +39
The VESPA data access system focuses on applying Virtual Observatory (VO) standards and tools to Planetary Science. Building on a previous EC-funded Europlanet program, it has reac…
Improving the surface brightness-color relation for early-type stars using optical interferometry
M. Challouf, N. Nardetto, D. Mourard +18
The aim of this work is to improve the SBC relation for early-type stars in the color domain, using optical interferometry. Observations of eight B- and A-type…
The diameter of the CoRoT target HD 49933. Combining the 3D limb darkening, asteroseismology, and interferometry
L. Bigot, D. Mourard, P. Berio +21
Context. The interpretation of stellar pulsations in terms of internal structure depends on the knowledge of the fundamental stellar parameters. Long-base interferometers permit us…
Chromosphere of K giant stars Geometrical extent and spatial structure detection
P. Berio, T. Merle, F. Thevenin +19
We aim to constrain the geometrical extent of the chromosphere of non-binary K giant stars and detect any spatial structures in the chromosphere. We performed observations with the…
The binary Be star δ Sco at high spectral and spatial resolution: Disk geometry and kinematics before the 2011 periastron
Anthony Meilland, O. Delaa, Philippe Stee +17
Classical Be stars are hot non-supergiant stars surrounded by a gaseous circumstellar disk that is responsible for the observed IR-excess and emission lines. The influence of binar…
Differential rotation in rapidly rotating early-type stars. I. Motivations for combined spectroscopic and interferometric studies
J. Zorec, Y. Fremat, A. Domiciano de Souza +7
Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may exist between the convection and the internal rotation.…
The fundamental parameters of the roAp star Equulei
K. Perraut, I. Brandão, D. Mourard +18
Physical processes working in the stellar interiors as well as the evolution of stars depend on some fundamental stellar properties, such as mass, radius, luminosity, and chemical…
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
N. Nardetto, D. Mourard, I. Tallon-Bosc +22
High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star bet…
Time, spatial, and spectral resolution of the Halpha line-formation region of Deneb and Rigel with the VEGA/CHARA interferometer
Olivier Chesneau, Luc Dessart, D. Mourard +22
BA-type supergiants are amongst the most optically-bright stars. They are observable in extragalactic environments, hence potential accurate distance indicators. Emission activity…
The H line forming region of AB Aur spatially resolved at sub-AU with the VEGA/CHARA spectro-interferometer
K. Perraut, M. Benisty, D. Mourard +19
A crucial issue in star formation is to understand the physical mechanism by which mass is accreted onto and ejected by a young star. The visible spectrometer VEGA on the CHARA arr…
