The SPHERE infrared survey for exoplanets (SHINE) -- II. Observations, Data reduction and analysis Detection performances and early-results

M. Langlois, R. Gratton, A. -M. Lagrange +118

Over the past decades, direct imaging has confirmed the existence of substellar companions (exoplanets or brown dwarfs) on wide orbits (>10 au) from their host stars. To understand…

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…

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…

Constraining the properties of HD 206893 B. A combination of radial velocity, direct imaging, and astrometry data

A. Grandjean, A. -M. Lagrange, H. Beust +25

High contrast imaging enables the determination of orbital parameters for substellar companions (planets, brown dwarfs) from the observed relative astrometry and the estimation of…
