TL;DR: In this article, the authors used the IRDIS dual-band imager and the IFS integral field spectrograph of SPHERE to acquire high-contrast coronagraphic differential near-infrared images and spectra of the young A2 star HIP.

TL;DR: In this article, the authors used SPHERE at the VLT to precisely monitor the orbital motion of beta Pictoris b since first light of the instrument in 2014, and were able to monitor the planet until November 2016, when its angular separation became too small (125 mas, i.e., 1.6 au) and prevented further detection.
