First light of the VLT planet finder SPHERE. I. Detection and characterization of the sub-stellar companion GJ 758 B

Vignette une

GJ 758 B is a brown dwarf companion to a nearby (15.76%) solar-type, metal-rich (M / H = + 0.2 dex) main-sequence star (G9V) that was discovered with Subaru/HiCIAO in 2009. From previous studies, it has drawn attention as being the coldest ( 600 K) companion ever directly imaged around a neighboring star. We present new high-contrast data obtained during the commissioning of the SPHERE (...)

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 with VLT/SPHERE

Vignette une

The young systemsPZ Tel and HD 1160, hosting known low-mass companions, were observed during the commissioning of the new planet finder of the Very Large Telescope (VLT) SPHERE with several imaging and spectroscopic modes.

First light of the VLT planet finder SPHERE III. New spectrophotometry and astrometry of the HR 8799 exoplanetary system

Vignette une

The planetary system discovered around the young A-type HR 8799 provides a unique laboratory to : a) test planet formation theories ; b) probe the diversity of system architectures at these separations, and c) perform comparative (exo)planetology.

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

Vignette une

The system of fourplanets discovered around the intermediate-mass star HR8799 offers a unique opportunity to test planet formation theories at large orbital radii and to probe the physics and chemistry at play in the atmospheres of self-luminous young ( 30 Myr) planets. We recently obtained new photometry of the four planets and low-resolution (R 30) spectra of HR8799 d and e with the SPHERE (...)

Characterizing HR 3549 B using SPHERE

Vignette une

HD 106906AB is the only young binary system so far around which a planet has been imaged and a debris disk has been shown to exist, thanks to a strong IR excess. As such, it represents a unique opportunity for studying the dynamics of young planetary systems.
