TL;DR: In this article, the authors reported the discovery in L' (3.8 microns) images of a probable companion orbiting at 56 AU the young (10-17 Myr), dusty, and early-type (A8) star HD 95086.

TL;DR: In this paper, K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY were presented.
High Contrast Imaging of the Close Environment of HD 142527
TL;DR: In this paper, the authors obtained deep thermal images of the close circumstellar environment of HD 142527 to re-image the reported close-in structures (cavity, spiral arms) of the disk and to search for stellar and substellar companions that could be connected to their presence.

TL;DR: In this article, the authors used the Gemini Planet Imager (GPI) to obtain new astrometry and a low-resolution (R=35-39) J-band spectrum of the planet.
