Fibered visible interferometry and adaptive optics: FRIEND at CHARA

Martinod, M. Mourard, D. Berio, P.

Aims. In the context of the future developments of long baseline interferometry at visible wavelengths, we have built a prototype instrument called Fibered spectrally Resolved Interferometer – New Design (FRIEND) based on single mode fibers and a new generation detector called Electron Multiplying Charge-Coupled Device (EMCCD). Installed on the...

The binary Be star δ Sco at high spectral and spatial resolution: Disk geometry and kinematics before the 2011 periastron

Meilland, Anthony Delaa, O. Stee, Philippe

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 binarity on these phenomena remains controversial. delta Sco is a binary system whose primary suddently began to exhibit the Be phenomenon at the last periastron in 2000....

The H α line forming region of AB Aurigae spatially resolved at sub-AU with the VEGA/CHARA spectro-interferometer

Rousselet-Perraut, K. Benisty, M. Mourard, D.

Context. A crucial issue in star formation is to understand the physical mechanism by which mass is accreted onto and ejected bya young star. To derive key constraints on the launching point of the jets and on the geometry of the winds, the visible spectro-polarimeter VEGA installed on the CHARA optical array can be an efficient means of...
