Méthode de type Maximum de Vraisemblance pour la détection d'exoplanètes par Imagerie Différentielle spectrale et angulaire

We propose a novel method for the efficient direct detection of exoplanets from the ground using spectral and angular differential imaging. The method combines images appropriately into “pseudo-data”, then uses all of them in a MaximumLikelihood framework to estimate the position and intensity of potential planets orbiting the observed star. The method has been tested on realistic simulations of images. 1 Contexte du travail et proble-
