The SPHERE infrared survey for exoplanets (SHINE)- I Sample definition and target characterization

S. Desidera, G. Chauvin, M. Bonavita +105

Large surveys with new-generation high-contrast imaging instruments are needed to derive the frequency and properties of exoplanet populations with separations from 5 to 300…

First light of the VLT planet finder SPHERE. II. The physical properties and the architecture of the young systems PZ Tel and HD 1160 revisited

A. -L. Maire, M. Bonnefoy, C. Ginski +68

[Abridged] Context. The young systems PZ Tel and HD 1160, hosting known low-mass companions, were observed during the commissioning of the new planet finder SPHERE with several ima…

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…

SPHERE: the exoplanet imager for the Very Large Telescope

J. -L. Beuzit, A. Vigan, D. Mouillet +108

Observations of circumstellar environments to look for the direct signal of exoplanets and the scattered light from disks has significant instrumental implications. In the past 15…

Shadowing and multiple rings in the protoplanetary disk of HD 139614

G. A. Muro-Arena, M. Benisty, C. Ginski +20

Shadows in scattered light images of protoplanetary disks are a common feature and support the presence of warps or misalignments between disk regions. These warps are possibly due…
