- AU Microscopii (AU Mic) is a young pre-main-sequence star located 9.79 parsecs away, featuring a unique edge-on debris disk that spans 35 to 210 astronomical units.
- Researchers detected a planet, AU Mic b, transiting the star, which has an orbital period of 8.46 days and a radius about 0.4 times that of Jupiter.
- The findings provide valuable data to test existing models of planet formation and evolution, especially in the context of magnetic activity related to the star.
We revisit the nulling interferometer performances that are needed for direct detection and the spectroscopic analysis of exoplanets, e.g., with the DARWIN [European Space Agency-SCI 12 (2000)] or TPF-I [JPL Publ.

In the area of long-baseline nulling interferometry, high rejection ratios are needed to cancel out the light of a bright central source and look for nearby faint structures or companions. These rejection requirements directly translate into drastic optical constraints. We discuss the possibility of using single-mode waveguides for such applications.
