Same as Fig. 1, but for the Serpens Emb 8(N) Class 0 protostellar core. The blue and red contours trace the moment 0 map of the blueshifted (by integrating emission from −10 to 6.5 km s⁻¹) and redshifted (by integrating emission from 10 to 21 km s⁻¹). The thick light blue contours (top right and bottom panels) trace the moment 0 map of the C₂H (by integrating emission from 5.4 to 12.8 km s⁻¹) and SO (by integrating emission from −16 to 8 km s⁻¹, and from 10.5 to 35.5 km s⁻¹) molecular emission spectral line. The ALMA band 0.87mm dust polarized emission, ALMA CO (J = 2 → 1) bipolar outflow emission, and C₂H emission line are from Le Gouellec et al. (2019). The SO emission line is from ALMA project 2019.1.00931.S, Tychoniec et al. (in prep.).
