Sketch (not to scale) of the proposed interpretation of the observations toward [BHB2007] 11 where a second outflow is found in addition to the CO outflow reported by Alves et al. (2017). The ellipses at the center represent the flattened envelope. The innermost contour represents the circumbinary disk, where the two stars of the system are represented by the stars. The inner ellipse represents the continuum contours from Figures 1 and 2, where the spiral structures seen in Alves et al. (2017) are emphasized. The tips of these spiral structures are the landing sites of the accretion from the envelope (blue and red arrows) and the launching points of the CO outflow (Alves et al. 2017). We marked the CO outflow from Alves et al. (2017) as Outflow 1, while the new proposed outflow inferred from the observations in this work is named Outflow 2. The launching point of Outflow 2 is unknown, and we draw it from the edge of the circumbinary disk. The SiO emission is represented with the thick contour at the center, corresponding to the 3σ contour from the left panel of Figure 2. The different molecular tracers used to identify each component of the system are overplotted on the sketch in the corresponding part. The rotation axes are indicated with the dashed lines. Blue and red represent blue- and redshifted velocities, respectively.
