SPHERE: the exoplanet imager for the Very Large Telescope

Jean-Luc Beuzit, +120 more
TL;DR: The Spectro-Polarimetic High contrast imager for Exoplanets REsearch (SPHERE) was designed and built for the ESO Very Large Telescope (VLT) in Chile as discussed by the authors.
Journal ArticleDOI

Discovery of a warm, dusty giant planet around HIP 65426

Gael Chauvin, +138 more
TL;DR: In this article, the authors used the IRDIS dual-band imager and the IFS integral field spectrograph of SPHERE to acquire high-contrast coronagraphic differential near-infrared images and spectra of the young A2 star HIP.
Journal ArticleDOI

First light of the VLT planet finder SPHERE IV : Physical and chemical properties of the planets around HR8799

M. Bonnefoy, +77 more
TL;DR: In this paper, the spectral energy distribution (SED) of HR8799d and e was compared to field dwarfs and young companions, and three sets of atmospheric models (BT-SETTL14, Cloud-AE60, Exo-REM) were used.
Journal ArticleDOI

Post-conjunction detection of β Pictoris b with VLT/SPHERE

A. M. Lagrange, +114 more
TL;DR: In this article, the authors used SPHERE at the VLT to precisely monitor the orbital motion of beta Pictoris b since first light of the instrument in 2014, and were able to monitor the planet until November 2016, when its angular separation became too small (125 mas, i.e., 1.6 au) and prevented further detection.
Journal ArticleDOI

The SPHERE infrared survey for exoplanets (SHINE) - II. Observations, data reduction and analysis, detection performances, and initial results

Maud Langlois, +138 more
TL;DR: In this article, the authors presented the observing and data analysis strategy, the ranking process of the detected candidates, and the survey performances for a subsample of 150 stars that are representative of the full SHINE sample.
