Photometric characterization of exoplanets using angular and spectral differential imaging
Arthur Vigan,Claire Moutou,Maud Langlois,Anthony Boccaletti,Marcel Carbillet,David Mouillet,I. Smith +6 more
TL;DR: In this article, the photometric error on the planet flux was investigated and the consequences on the determination of the physical parameters of the detected exoplanets were investigated and a detailed end-to-end simulation with the CAOS-based Software Package for SPHERE was performed to obtain realistic data representing typical observing sequences in Y, J, H and Ks bands with a high contrast imager.

Marcel Carbillet,Anthony Boccaletti,Christian Thalmann,Thierry Fusco,Arthur Vigan,I. Smith,David Mouillet,Kjetil Dohlen,P. Bendjoya,Andrea Ferrari +9 more
TL;DR: SPHERE (Spectro-Polarimetric High-contrast Exoplanet REsearch) is the second-generation VLT instrument devoted primarily to direct imaging and characterization of exoplanets, and allowing a large number of promising observations modes as mentioned in this paper.

Photometric exoplanet characterization with angular and spectral differential imaging
Arthur Vigan,Claire Moutou,Maud Langlois,Anthony Boccaletti,Marcel Carbillet,David Mouillet,I. Smith +6 more
TL;DR: In this article, the authors investigate the photometric error and the consequences on the determination of the physical parameters of the detected planets and apply this empirical accuracy to study the characterization capabilities of a high-contrast differential imager.
