Revisiting the atmosphere of the exoplanet 51 Eridani b with VLT/SPHERE
S. B. Brown-Sevilla, A. -L. Maire, P. Mollière +27
[Full abstract in the paper] We aim to better constrain the atmospheric properties of the directly imaged exoplanet 51~Eri~b by using a retrieval approach on higher signal-to-noise…
An extended scattered light disk around AT Pyx -- Possible planet formation in a cometary globule
C. Ginski, R. Gratton, A. Bohn +35
To understand how the multitude of planetary systems that have been discovered come to be, we need to study systems at different evolutionary stages, with different central stars b…
Signs of late infall and possible planet formation around DR Tau using VLT/SPHERE and LBTI/LMIRCam
D. Mesa, C. Ginski, R. Gratton +31
Context. Protoplanetary disks around young stars often contain substructures like rings, gaps, and spirals that could be caused by interactions between the disk and forming planets…
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…
The SPHERE infrared survey for exoplanets (SHINE). III. The demographics of young giant exoplanets below 300 au with SPHERE
A. Vigan, C. Fontanive, M. Meyer +108
The SHINE project is a 500-star survey performed with SPHERE on the VLT for the purpose of directly detecting new substellar companions and understanding their formation and early…
HD 117214 debris disk: scattered-light images and constraints on the presence of planets
N. Engler, C. Lazzoni, R. Gratton +34
We performed observations of the Sco-Cen F star HD 117214 aiming at a search for planetary companions and the characterization of the debris disk structure. HD 117214 was observed…
First resolved observations of a highly asymmetric debris disc around HD 160305 with VLT/SPHERE
Clément Perrot, Philippe Thebault, Anne-Marie Lagrange +36
Context. Direct imaging of debris discs gives important information about their nature, their global morphology, and allows us to identify specific structures possibly in connectio…
Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
M. Keppler, M. Benisty, A. Müller +123
Young circumstellar disks are of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of planet cand…
Imaging radial velocity planets with SPHERE
A. Zurlo, D. Mesa, S. Desidera +37
We present observations with the planet finder SPHERE of a selected sample of the most promising radial velocity (RV) companions for high-contrast imaging. Using a Monte Carlo simu…
Discovery of a brown dwarf companion to the star HIP 64892
A. Cheetham, M. Bonnefoy, S. Desidera +89
We report the discovery of a bright, brown dwarf companion to the star HIP 64892, imaged with VLT/SPHERE during the SHINE exoplanet survey. The host is a B9.5V member of the Lower-…
Discovery of a warm, dusty giant planet around HIP65426
G. Chauvin, S. Desidera, A. -M. Lagrange +120
The SHINE program is a large high-contrast near-infrared survey of 600 young, nearby stars. It is aimed at searching for and characterizing new planetary systems using VLT/SPHERE's…
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…
First light of the VLT planet finder SPHERE. I. Detection and characterization of the sub-stellar companion GJ 758 B
A. Vigan, M. Bonnefoy, C. Ginski +72
GJ758 B is a brown dwarf companion to a nearby (15.76 pc) solar-type, metal-rich (M/H = +0.2 dex) main-sequence star (G9V) that was discovered with Subaru/HiCIAO in 2009. From prev…
First light of the VLT planet finder SPHERE. III. New spectrophotometry and astrometry of the HR8799 exoplanetary system
A. Zurlo, A. Vigan, R. Galicher +70
The planetary system discovered around the young A-type HR8799 provides a unique laboratory to: a) test planet formation theories, b) probe the diversity of system architectures at…
