Left panel: map of the emission from L₂ Pup in the ²⁹SiO(ν= 0,J = 8−7) line (left), integrated between radial velocities −30 and + 30 km s^-1 around the systemic velocity (v₀ = 33 km s^-1). The pseudo-slit used to compute the position-velocity diagrams is represented with solid white lines. The linear color scale in Jy beam^-1 km s^-1 is shown in the lower right corner, and the beam size is represented by the ellipse in the lower left corner of the image. The radius of the inner rim (6 AU) and the radius of the companion of L₂ Pup are shown with magenta and cyan triangles, respectively. Right panel: map of the first moment emission of the velocity (the color scale is in km s^-1). The contours are drawn between 4 and 10 km s^-1 with a 2 km s^-1 step, and the size of the photosphere is shown with a light green disk.
