摘要：

The combination of adaptive optics and coronographic techniques providing at the same time high angular resolution and high dynamic range is a powerful tool to study the close environment of bright objects in different fields of astrophysics (search for brown dwarfs around nearby stars, search for circumstellar disks, study of the AGE outflows, etc.). A stellar coronograph dedicated to the ESO adaptive optics system ADONIS has been designed and manufactured by Observatoire de Grenoble and is now offered to the astronomical community. We present here the design and performance analysis of this new coronograph and illustrate its impact for a few astrophysical programmes.
