We present in this paper the latest news about the adaptive optics facility bench LOOPS at LAM. A review of the scheme of the bench is first given, going through the optical path module after module. The first results obtained with a spatial light modulator, used to produce high-definition reprogrammable focal phase mask, are then presented.

Over the past 2.5 years, we have been carrying out disc-resolved observations of a substantial fraction of all large (D > 100 km) main-belt asteroids, monitoring them at high angular resolution throughout their rotation, and sampling the main compositional classes, using the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE)...

In the context of the SPHERE planet finder project, we further develop and characterize a recently proposed method for the efficient direct detection of exoplanets from the ground using spectral and angular differential imaging. The method, called ANDROMEDA, combines images appropriately into "pseudo-data", then uses all of them in a...
