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…
PERSEE: Experimental results on the cophased nulling bench
Julien Lozi, Frédéric Cassaing, Jean-Michel Le Duigou +15
Nulling interferometry is still a promising method to characterize spectra of exoplanets. One of the main issues is to cophase at a nanometric level each arm despite satellite dist…
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…
