This paper presents the current status of the VEGA (Visible spEctroGraph and polArimeter) instrument installed at the coherent focus of the CHARA Array, Mount Wilson CA. Installed in september 2007, the first science programs have started during summer 2008 and first science results are now published. Dedicated to high angular (0.3mas) and high...

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...

The Solar System Odyssey mission uses modern-day high-precision experimental techniques to answer some of the important questions on the laws of fundamental physics which determine dynamics in the solar system. It could lead to a major discovery by using readily available technologies and could be flown early within the Cosmic Vision time...
