Mid-IR Water-Vapor Seeing: Implications for ELT/METIS High-Contrast Imaging from VLTI Data

Abhirami S Raghu, Prashant Pathak, Olivier Absil +7

Direct imaging and characterization of rocky exoplanets remains one of the central challenges in exoplanetary science. The mid-infrared (mid-IR) offers a favorable high-contrast im…

MATISSE in the era of GRAVITY+

Florentin Millour, Anthony Soulain, St{é}phane Lagarde +28

MATISSE, the mid-infrared spectro-interferometric imager of the Very Large Telescope Interferometer (VLTI), has been feeding on the light corrected by the GRAVITY+ Adaptive Optics…

Interferometric Survey of Stellar Parameters: Towards homogeneous FGK stars parameters and surface-brightness color relation in the context of PLATO space mission

Romina V. Ibañez Bustos, Denis Mourard, Nicolas Nardetto +20

The estimation of stellar angular diameters can be performed from the surface brightness - color relation (SBCR) and photometry. The SBCR have been considered by the PLATO space mi…

GRAVITY+ adaptive optics (GPAO) tests in Europe

Florentin Millour, Guillaume Bourdarot, Jean-Baptiste Le Bouquin +54

We present in this proceeding the results of the test phase of the GRAVITY+ adaptive optics. This extreme AO will enable both high-dynamic range observations of faint companions (i…

Open loop calibration and closed loop non-perturbative estimation of the lateral errors of an adaptive optics system: examples with GRAVITY+ and CHARA experimental data

Anthony Berdeu, Henri Bonnet, Jean-Baptiste Le Bouquin +15

Performances of an adaptive optics (AO) system are directly linked with the quality of its alignment. During the instrument calibration, having open loop fast tools with a large ca…

Asgard/NOTT: water vapor and CO atmospheric dispersion compensation system

Romain Laugier, Denis Defrère, Michael Ireland +8

To leverage the angular resolution of interferometry at high contrast, one must employ specialized beam-combiners called interferometric nullers. Nullers discard part of the astrop…
