Experimental test of a 40 cm-long R=100 000 spectrometer for exoplanet characterisation
Guillaume Bourdarot, Etienne Le Coarer, David Mouillet +12
High-resolution spectroscopy is a key element for present and future astronomical instrumentation. In particular, coupled to high contrast imagers and coronagraphs, high spectral r…
A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE
G. Cugno, S. P. Quanz, S. Hunziker +37
Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…
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…
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…
