TL;DR: In this paper, the spectral energy distribution (SED) of HR8799d and e was compared to field dwarfs and young companions, and three sets of atmospheric models (BT-SETTL14, Cloud-AE60, Exo-REM) were used.

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.
