Left: Column density map of part of the Taurus molecular cloud as derived from Herschel Gould Belt Survey Archive data1 (cf. Palmeirim et al. 2013). The B211/3 well-studied filament and the L1495 star-forming hub are indicated. The red rectangle shows the region analyzed in this paper. Middle: Blow-up column density map, at the resolution of 28″, of the red rectangle plotted in the left panel. The black contours are at column densities of 4, 6, and 8 × 1021cm−2. The blue- and red-white triangles are the prestellar cores and the unbound fragments identified by Marsh et al. (2016), respectively. The white dashed contour shows the footprint of the CO maps observed with the Nobeyama 45 m telescope. Right: The map is the same as the middle panel. The blue and red skeletons trace the crests of the two filaments discussed in this paper, MF and YF, respectively. (Color online)
