The Software Package AIRY (acronym of Astronomical Image Restoration in interferometrY) is a complete tool for the simulation and the deconvolution of astronomical images. The data can be a post-Adaptive-optics image of a single dish telescope or a set of multiple images of a Fizeau interferometer. Written in IDL and freely downloadable, AIRY...

We report in this communication the rst experimental results in the visible range obtained by the Probability Imaging technique applied to close binary stars. Speckle data of the well known binary Del as well as the newly discovered one Moai1 (Carbillet et al. 1996) are processed. An analysis of the probability density functions, combined with...

Exoplanets imaging requires very high angular resolution that will be reached with the forthcoming generation of extremely large telescopes. In order to achieve the high performance required for the astronomical science programs, the errors due to segment misalignment must be reduced to tens of nm. Therefore the development of new co-phasing...

Adaptive optics systems require a calibration procedure to operate, whether in closed loop or even more importantly in forward control. This calibration usually takes the form of an interaction matrix and is a measure of the response on the wavefront sensor to wavefront corrector stimulus. If this matrix is sufficiently well conditioned, it can...

Nous présentons de nouveaux éléments orbitaux pour l'étoile double visuelle WDS~02193-0259 (JOY~1~Aa ADS~1778). Ces éléments ont été obtenus en utilisant les dernières mesures que nous avons effectuées avec le tavelographe PISCO et le télescope Bernard Lyot de 2 m du Pic du Midi, et celles déjà disponibles dans la littérature.

This paper presents speckle observations of Mira (o Cet) and late-type stars with the PISCO speckle camera of Pic du Midi during the period 1995-1998. A survey for binarity among a sample of late-type stars was performed, which led to 7 positive detections out of 36 objects. Photometric and color variations of the companion of Mira were...
