Polarized intensity and molecular line observations around the B335 Class 0 protostellar core (as in Figure 1). The thick light blue contours trace the moment 0 map of the CS (from 6 to 11 km s⁻¹) and c-C₃H₂ (from 7 to 9.5 km s⁻¹) molecular emission spectral line, at levels of 3, 5, 7, 9, 11, 16, 24, 44 × the rms noise level of each map. In the bottom left corner of each plot the ellipses represent the beam resolution element of a given dataset: yellow for polarized dust emission; white for the CS and c-C₃H₂ spectral emission lines. ALMA 1.3mm dust polarized emission from Maury et al. (2018) and Maury et al. (in prep.). The CS and c-C₃H₂ emission lines are from Imai et al. (2016).
