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…

Gap, shadows, spirals, streamers: SPHERE observations of binary-disk interactions in GG Tau A

M. Keppler, A. Penzlin, M. Benisty +31

A large fraction of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question if and how planets i…

TOI-269 b: An eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA

M. Cointepas, J. M. Almenara, X. Bonfils +59

We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI- 269 (TIC 220479565, V = 14.4 mag, J = 10…

Upgrading the high contrast imaging facility SPHERE: science drivers and instrument choices

A. Boccaletti, G. Chauvin, F. Wildi +71

SPHERE+ is a proposed upgrade of the SPHERE instrument at the VLT, which is intended to boost the current performances of detection and characterization for exoplanets and disks. S…

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…
