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…
A single-armed spiral in the protoplanetary disk around HD34282 ?
J. de Boer, C. Ginski, G. Chauvin +17
During the evolution of protoplanetary disks into planetary systems we expect to detect signatures that trace mechanisms such as planet-disk interaction. Protoplanetary disks displ…
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…
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…
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-…
First scattered light detection of a nearly edge-on transition disk around the T Tauri star RY Lup
M. Langlois, A. Pohl, A. -M. Lagrange +41
Transition disks are considered sites of ongoing planet formation, and their dust and gas distributions could be signposts of embedded planets. The transition disk around the T Tau…
Investigation of the inner structures around HD169142 with VLT/SPHERE
R. Ligi, A. Vigan, R. Gratton +47
We present observations of the Herbig Ae star HD169142 with VLT/SPHERE instruments InfraRed Dual-band Imager and Spectrograph (IRDIS) ( and bands) and the Integral Fie…
Orbiting a binary: SPHERE characterisation of the HD 284149 system
Mariangela Bonavita, V. D'Orazi, D. Mesa +52
In this paper we present the results of the SPHERE observation of the HD 284149 system, aimed at a more detailed characterisation of both the primary and its brown dwarf companion.…
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…
Testing giant planet formation in the transitional disk of SAO 206462 using deep VLT/SPHERE imaging
A. -L. Maire, T. Stolker, S. Messina +42
Context. The SAO 206462 (HD 135344B) disk is one of the few known transitional disks showing asymmetric features in scattered light and thermal emission. Near-infrared scattered-li…
Shadows and spirals in the protoplanetary disk HD 100453
M. Benisty, T. Stolker, A. Pohl +46
Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form. We observed and spatially resolv…
