Best fit of AK Sco’s radial velocities and interferometric data with the binary+ring model. From top left to bottom right: upper left: apparent trace of the best-fit orbit of the binary (primary at 0, 0) with the time of observation; upper right: radial velocity from Alencar with the best-fit orbit; middle left: comparison between model and PIONIER observation for V2; middle right: comparison between model and PIONIER observations for closure phases; lower left: full model of disk + binary as projected on the sky; lower right: full model of disk + binary as seen pole-on.
