NaCo polarimetric observations of Sz 91 transitional disk: a remarkable case of dust filtering

Karina Maucó, Johan Olofsson, Hector Canovas +10

We present polarized light observations of the transitional disk around Sz 91 acquired with VLT/NaCo at (1.7m) and (2.2m) bands. We resolve the disk and detect pola…

Long lived dust rings around HD169142

Claudia Toci, Giuseppe Lodato, Davide Fedele +2

Recent ALMA observations of the protoplanetary disc around HD~169142 reveal a peculiar structure made of concentric dusty rings: a main ring at 20 au, a triple system of ring…

Flybys in protoplanetary discs: II. Observational signatures

Nicolás Cuello, Fabien Louvet, Daniel Mentiplay +14

Tidal encounters in star clusters perturb discs around young protostars. In Cuello et al. (2019a, Paper I) we detailed the dynamical signatures of a stellar flyby in both gas and d…

Signatures of an eccentric disc cavity: Dust and gas in IRS 48

Josh Calcino, Daniel J. Price, Christophe Pinte +5

We test the hypothesis that the disc cavity in the `transition disc' Oph IRS 48 is carved by an unseen binary companion. We use 3D dust-gas smoothed-particle hydrodynamics simulati…

An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light

Bin Ren, Élodie Choquet, Marshall D. Perrin +70

We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…

Evidence for a circumplanetary disk around protoplanet PDS 70 b

V. Christiaens, F. Cantalloube, S. Casassus +5

We present the first observational evidence for a circumplanetary disk around the protoplanet PDS~70~b, based on a new spectrum in the band acquired with VLT/SINFONI. We tested…
