The MICADO first light imager for the ELT: the SCAO module AIT in France, from the beta flat configuration towards the flat and final configurations

Yann Clénet, Vincent Lapeyrère, Eric Gendron +45

MICADO is the designated ELT first light instrument, a near-infrared imager working at the diffraction limit of the telescope thanks to a SCAO and an MCAO mode. Since summer 2024,…

Peering into the formation history of beta Pictoris b with VLTI/GRAVITY long baseline interferometry

GRAVITY Collaboration, M. Nowak, S. Lacour +65

Our objective is to estimate the C/O ratio in the atmosphere of beta Pictoris b and obtain an estimate of the dynamical mass of the planet, as well as to refine its orbital paramet…
