Asgard/NOTT: L-band nulling interferometry at the VLTI I. Simulating the expected high-contrast performance

Romain Laugier, Denis Defrère, Benjamin Courtney-Barrer +13

Context: NOTT (formerly Hi-5) is a new high-contrast L' band (3.5-4.0 \textmu m) beam combiner for the VLTI with the ambitious goal to be sensitive to young giant exoplanets down t…

Impact of water vapor seeing on mid-infrared high-contrast imaging at ELT scale

Olivier Absil, Christian Delacroix, Gilles Orban de Xivry +9

The high-speed variability of the local water vapor content in the Earth atmosphere is a significant contributor to ground-based wavefront quality throughout the infrared domain. U…

Locating dust and molecules in the inner circumstellar environment of R~Sculptoris with MATISSE

Julien Drevon, Florentin Millour, Pierre Cruzalèbes +49

AGB stars are one of the main sources of dust production in the Galaxy. However, it is not clear what this process looks like and where the dust is condensing in the circumstellar…

L-band nulling interferometry at the VLTI with Asgard/Hi-5: status and plans

Denis Defrère, Azzurra Bigioli, Colin Dandumont +34

Hi-5 is the L'-band (3.5-4.0 m) high-contrast imager of Asgard, an instrument suite in preparation for the visitor focus of the VLTI. The system is optimized for high-contrast a…

The disk of FU Orionis viewed with MATISSE/VLTI: first interferometric observations in and bands

F. Lykou, P. Ábrahám, L. Chen +30

The disk of FU Orionis is marginally resolved with MATISSE, suggesting that the region emitting in the thermal infrared is rather compact. An upper limit of mas (in…

Improving the diameters of interferometric calibrators with MATISSE

S. Robbe-Dubois, P. Cruzalèbes, Ph. Berio +16

A good knowledge of the angular diameters of stars used to calibrate the observables in stellar interferometry is fundamental. As the available precision for giant stars is worse t…
