Evolution of the bar characteristics (left column) in relatively less massive barred (red), short-bar (green), and unbarred (blue) galaxies with log (M_{*, 30 kpc}/M_⊙) = 10.6 − 10.8 in TNG100 and the evolution of some parameters of the galaxies (middle and right columns). The left column displays the evolution of the bar size (R_bar) obtained from ellipse fitting (middle panel) and the evolution of bar fraction for the sample of galaxies based (top panel). It also presents the evolution of A_2, max obtained from Fourier decomposition (bottom panel). The middle column shows the evolution of stellar mass (M_*), central gas mass (M_gas), and supermassive black hole mass (M_BH). The right column shows the evolution of the stellar surface mass density within R_e (Σ_Re), the central 1 kpc stellar surface mass density (Σ_1 kpc) and the ratio of kinetic energy over ordered rotation (κ_rot). For all the panels, the x-axis is lookback time, which equals z = 0 when lookback time = 0 Gyr, and z = 1 when lookback time ≈ 8 Gyr. The solid lines represent the median values of each distribution, with colored regions indicating the 16–84th percentile range.
