Image Details
Caption: Figure 3.
(Top panels) Velocity gradient maps for (a) K04166, (b) K04169, and (c) Miz-8b. The length and angle of each black arrow correspond to the magnitude and direction, respectively, of the local velocity gradient. A reference arrow with units of kilometers per second per parsec is shown on each plot. Red segments show the B-field orientations from Figure 1(b). (Bottom panels) Weighted mean B-field geometry (thick red segments; same as Figure 2) in the cores of (d) K04166, (e) K04169, and (f) Miz-8b, overlaid on the Stokes I map (color scale). The large-scale Planck mean B-field direction is shown as a yellow segment on each core. Red and blue contours show the redshifted and blueshifted 12CO (2–1) emission tracing the bipolar outflow in the center of each core. These were obtained with the ALMA 7 m array by Tokuda et al. (2020). The cyan line denotes the mean PA of each outflow (33° for K04166 and 58° for K04169). The thin black line represents the PA of the core rotation axis. The integrated velocity ranges are −10 to 0 and 10 to 20 km s−1 for the blue- and redshifted outflows of K04166 and −5 to 4 and 11 to 17 km s−1 for the blue- and redshifted outflows of K04169. The lowest and subsequent contour steps are 0.4 and 1.2 K km s−1 , respectively. The angular resolution of the ALMA data is 6.″8 × 6.″5.
