Title: Three years of SPHERE: the latest view of the morphology and evolution of protoplanetary discs,
Abstract: Spatially resolving the immediate surroundings of young stars is a key
challenge for the planet formation community. SPHERE on the VLT represents an
important step forward by increasing the opportunities offered by optical or
near-infrared imaging instruments to image protoplanetary discs. The Guaranteed
Time Observation Disc team has concentrated much of its efforts on polarimetric
differential imaging, a technique that enables the efficient removal of stellar
light and thus facilitates the detection of light scattered by the disc within
a few au from the central star. These images reveal intriguing complex disc
structures and diverse morphological features that are possibly caused by
ongoing planet formation in the disc. An overview of the recent advances
enabled by SPHERE is presented.
