Active and Adaptive Optics

Abstract. The detection of faint emissions very close to much brighter objects is required in several different fields of astrophysics, for example in the search for planetary disks. We present here a coronograph that we built to work with come-on-plus, the ESO adaptive optics system, high angular resolution being of key importance in allowing observations close to a central, occulted object. The first results are presented and analyzed in order to establish the performance of this instrument in terms of contrast and detectability of faint emissions close to a central star.
