Optical gains measurement with a gain scheduling camera: On-sky demonstration with PAPYRUS and perspectives

A. Striffling, C. -T. Héritier, R. J. -L Fétick +4

Reaching the high angular resolution and contrast level desired for exoplanetary science requires us to equip large telescopes with extreme adaptive optics (XAO) systems to compens…

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…

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

M. Bonnefoy, A. Zurlo, J. L. Baudino +63

The system of four planets around HR8799 offers a unique opportunity to probe the physics and chemistry at play in the atmospheres of self-luminous young (~30 Myr) planets. We rece…
