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…
