SPHERE - Spectro-Polarimetric High-contrast Exoplanet REsearch


SPHERE is the extreme adaptive optics system and coronagraphic facility at the VLT. Its primary science goal is imaging, low-resolution spectroscopic, and polarimetric characterization of extra-solar planetary systems at optical and near-infrared wavelengths.

Publications based on data obtained with the SPHERE instrument should quote the following reference paper: Beuzit et al., 2019 (A&A 631, A155). They should also cite the appropriate references for the observing modes that were used.
