Overview of the MATISSE observations of RY Tau listed in Table 1. The corresponding u–v coordinates are shown in Fig. 4. Left panel: Squared visibilities, V², over projected baseline length B_p (pink/red: 8–13 μm wavelengths; blue/green: 3.5–5.2 μm wavelengths; see color bars). Middle panel: Measured closure phases, ϕ_cp, over the longest projected baseline length in the telescope triplet, B_p;max. Right panel: Correlated fluxes, F_corr, and corresponding projected baseline length, B_p, and orientation, ϕ_B, in the N band.
