Same as Fig. 1, but for the Serpens Emb 8 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 4.4 to 12.6 km s⁻¹) and SO (by integrating emission from −1.5 to 15.5 km s⁻¹) molecular emission spectral line. ALMA band 0.87mm dust polarized emission is from Hull et al. (2017a). ALMA CO (J = 2 → 1) bipolar outflow emission is from Le Gouellec et al. (2019). C₂H and SO emission line is from van Gelder et al. (2020) and Tychoniec et al. (2021).
