Dust continuum emission in color scale with a resolution of 0.″1 (∼2.6 mpc or ∼540 au) around 230 GHz (∼1.3 mm) in Band 6 with ALMA for W51 e2, except the upper left panel, which shows the earlier still more roundish detection with a 0.″26 resolution (Koch et al. 2018). White segments display the magnetic field in the right panels at half of the synthesized beam resolution (white ellipses in the lower left corners). Outflows are overplotted in the bottom middle and right panel. The cyan and faint-red contours denote the blue- and redshifted 12CO 2−1 outflow component, and the blue and red contours mark the blue- and redshifted SiO 5−4 outflow emission. Dust lanes and streamers are labeled in the bottom left panel, where continuum contours are identical to the ones described in the right panels in Figure 8. The bottom right panel marks the sectors of nearly straight field lines (yellow rectangles) and the possible small disk (black ellipse) as discussed in Section 3.
