Integrated intensity maps of the detected lines, and of the 855 μm continuum (Isella et al. 2019), with the white contours showing the bright ring in the submillimeter continuum emission and the white dots marking the position of the two forming planets (Wang et al. 2021). Brightness temperatures were obtained under the assumption of Rayleigh-Jeans approximation. The white ellipse at the bottom left of each panel is the beam, while the white line at the bottom right of the last panel indicates the 100 au scale.
