Orbital and dynamical analysis of the system around HR 8799. New astrometric epochs from VLT/SPHERE and LBT/LUCI

A. Zurlo, K. Gozdziewski, C. Lazzoni D. Mesa +44

HR\,8799 is a young planetary system composed of 4 planets and a double debris belt. Being the first multi-planetary system discovered with the direct imaging technique, it has bee…

New binaries from the SHINE survey

M. Bonavita, R. Gratton, S. Desidera +67

We present the multiple stellar systems observed within the SpHere INfrared survey for Exoplanet (SHINE). SHINE searched for substellar companions to young stars using high contras…

Investigating three Sirius-like systems with SPHERE

R. Gratton, V. D'Orazi, T. A. Pacheco +61

Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…

The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B

C. Lazzoni, A. Zurlo, S. Desidera +45

In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. In this paper, we focus our attention on substellar c…

Characterising brown dwarf companions with IRDIS long-slit spectroscopy: HD 1160 B and HD 19467 B

D. Mesa, V. D'Orazi, A. Vigan +9

The determination of the fundamental properties (mass, separation, age, gravity and atmospheric properties) of brown dwarf companions allows us to infer crucial informations on the…

First resolved observations of a highly asymmetric debris disc around HD 160305 with VLT/SPHERE

Clément Perrot, Philippe Thebault, Anne-Marie Lagrange +36

Context. Direct imaging of debris discs gives important information about their nature, their global morphology, and allows us to identify specific structures possibly in connectio…
