Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood

Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62

The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…

Simplified model(s) of the GRAVITY+ adaptive optics system(s) for performance prediction

Anthony Berdeu, Jean-Baptiste Le Bouquin, Guillaume Mella +13

In the context of the GRAVITY+ upgrade, the adaptive optics (AO) systems of the GRAVITY interferometer are undergoing a major lifting. The current CILAS deformable mirrors (DM, 90…

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…

VLTI Unit Telescope coudé train vibration control upgrade for GRAVITY+

Romain Laugier, Julien Woillez, Denis Defrère +15

Scaling up interferometry to 8m collectors should smooth-out the optical piston perturbations and allow a slow fringe tracker to obtain high precision correction on faint targets.…

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…
