Multiple Star Systems in the Orion Nebula
GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133
This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…
GRAVITY chromatic imaging of Eta Car's core
GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132
Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…
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…
The GJ 504 system revisited. Combining interferometric, radial velocity, and high contrast imaging data
M. Bonnefoy, K. Perraut, A. -M. Lagrange +79
The G-type star GJ504A is known to host a 3 to 35 MJup companion whose temperature, mass, and projected separation all contribute to make it a test case for the planet formation th…
Orbital and atmospheric characterization of the planet within the gap of the PDS 70 transition disk
A. Müller, M. Keppler, Th. Henning +43
Aims: We aim to characterize the orbital and atmospheric properties of PDS 70 b, which was first identified on May 2015 in the course of the SHINE survey with SPHERE, the extreme a…
Characterisation of ALPAO deformable mirrors for the NAOMI VLTI Auxiliary Telescopes Adaptive Optics
Jean-Baptiste Le Bouquin, Jean-Philippe Berger, Jean-Luc Beuzit +12
The Very Large Telescope Interferometer Auxiliary Telescopes will soon be equipped with an adaptive optics system called NAOMI. The corrective optics deformable mirror is the comme…
The SPHERE view of Wolf-Rayet 104
A. Soulain, F. Millour, B. Lopez +16
Context. WR104 is an emblematic dusty Wolf-Rayet star and the prototypical member of a subgroup hosting spirals that are mainly observable with high-angular resolution techniques.…
Orbital and spectral analysis of the benchmark brown dwarf HD 4747B
S. Peretti, D. Ségransan, B. Lavie +43
The study of high contrast imaged brown dwarfs and exoplanets depends strongly on evolutionary models. To estimate the mass of a directly imaged substellar object, its extracted ph…
Resolving faint structures in the debris disk around TWA7
J. Olofsson, R. G. van Holstein, A. Boccaletti +51
Debris disks are the intrinsic by-products of the star and planet formation processes. Most likely due to instrumental limitations and their natural faintness, little is known abou…
VLT/SPHERE astrometric confirmation and orbital analysis of the brown dwarf companion HR 2562 B
A. -L. Maire, L. Rodet, C. Lazzoni +46
Context. A low-mass brown dwarf has been recently imaged around HR 2562 (HD 50571), a star hosting a debris disk resolved in the far infrared. Interestingly, the companion location…
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-…
