High contrast at short separation with VLTI/GRAVITY: Bringing Gaia companions to light
N. Pourré, T. O. Winterhalder, J. -B. Le Bouquin +173
Since 2019, GRAVITY has provided direct observations of giant planets and brown dwarfs at separations of down to 95 mas from the host star. Some of these observations have provided…
A catalogue of dual-field interferometric binary calibrators
M. Nowak, S. Lacour, R. Abuter +97
Dual-field interferometric observations with VLTI/GRAVITY sometimes require the use of a "binary calibrator", a binary star whose individual components remain unresolved by the int…
First light of VLT/HiRISE: High-resolution spectroscopy of young giant exoplanets
A. Vigan, M. El Morsy, M. Lopez +46
A major endeavor of this decade is the direct characterization of young giant exoplanets at high spectral resolution to determine the composition of their atmosphere and infer thei…
Lessons learned from SPHERE for the astrometric strategy of the next generation of exoplanet imaging instruments
A. -L. Maire, M. Langlois, P. Delorme +14
Measuring the orbits of directly-imaged exoplanets requires precise astrometry at the milliarcsec level over long periods of time due to their wide separation to the stars ($\gtrsi…
High-precision astrometric studies in direct imaging with SPHERE
A. -L. Maire, G. Chauvin, A. Vigan +15
Orbital monitoring of exoplanetary and stellar systems is fundamental for analysing their architecture, dynamical stability and evolution, and mechanisms of formation. Current high…
Design, pointing control, and on-sky performance of the mid-infrared vortex coronagraph for the VLT/NEAR experiment
A. -L. Maire, E. Huby, O. Absil +16
Vortex coronagraphs have been shown to be a promising avenue for high-contrast imaging in the close-in environment of stars at thermal infrared (IR) wavelengths. They are included…
