Evolution of green BSs from z = 0.5 to z = 0 for the three green BS sub-types. The panels display, from top to bottom: the sSFR, the gas fraction relative to M_⋆ + M_gas, and the stellar mass normalised to its value at z = 0.5. Solid and dashed lines represent trends for high- and low-mass galaxies, respectively, with shaded regions indicating bootstrap-derived error bars. For comparison, the results found in Fig. 5 for the total sample of green BSs are reproduced across all properties. The horizontal light grey line indicates the threshold for classifying galaxies as SF or PS. The vertical lines mark the median entry and exit times of green BSs from the group’s R₂₀₀.
