H₂ number density (solid lines, left y-axis) of critical 0.25   M_⊙ type 1 (OH94, blue) and type 2 (LD01, red) MBESs as a function of radial distance from core center. Also plotted is the density profile of the critical 0.25   M_⊙ BES corresponding to the mean temperature of the type 1 MBES (green solid line; see text). The temperature profiles of the respective cores are plotted as dashed lines (right y-axis).
