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…
NAOMI: the adaptive optics system of the Auxiliary Telescopes of the VLTI
Woillez J., Abad J. A., Abuter R. +80
The tip-tilt stabilisation system of the 1.8 m Auxiliary Telescopes of the Very Large Telescope Interferometer was never dimensioned for robust fringe tracking, except when atmosph…
Speckle Temporal Stability in eXtreme Adaptive Optics Coronagraphic Images
P. Martinez, C. Loose, E. Aller Carpentier +1
The major noise source limiting high-contrast imaging is due to the presence of quasi-static speckles. Speckle noise originates from wavefront errors caused by various independent…
