Objectives of SPHERE-DC

Context The main scientific objective of the SPHERE instrument at VLT (Spectro-Polarimetric High-contrast Exoplanet REsearch) is to detect and characterize, using direct imaging techniques, young giant exoplanets orbiting around nearby stars. This instrument also allows to detect and characterize disks around young stars in which planet forms. This is a huge challenge since these planets (...)
