Environment of young stars: from adaptive optics to telescope arrays.
Abstract
Protoplanetary disks around young stars can now be observed with a 0.1″angular resolution using adaptive optics. These observations bring a new vision of the primordial solar nebula. Unfortunately, the close surroundings of the star are masked by its glare. A new stellar coronagraph with a phase mask should enable one to observe much closer to the central star. The technique applies to images produced by telescope arrays. It could allow to detect planets at distances as close as that between the Earth and the Sun.
