Context. 51 Eridani b is an exoplanet around a young (20 Myr) nearby (29.4 pc) F0‐type star, which was recently discovered by direct imaging. It is one of the closest direct imaging planets in angular and physical separation (similar to 0.5 `', similar to 13 au) and is well suited for spectroscopic analysis using integral field spectrographs....

Context. The 51 Eridani system harbors a complex architecture with its primary star forming a hierarchical system with the binary GJ 3305AB at a projected separation of 2000 au, a giant planet orbiting the primary star at 13 au, and a low-mass debris disk around the primary star with possible cold and warm components inferred from the spectral...
