Updated nuclear disc mass buildup. In this plot, we present the updated result from de Sá-Freitas et al. (2025) of the nuclear disc mass normalized by the galaxy mass for different bar ages, colour-coding each point according to its Σ_SFR, which increases towards blue colours (original Figure 9). The updated result is qualitatevely the same, as the bars age, the nuclear discs gradually become less star-forming and their masses increase (updated correlation coefficient 0.7 ± 2 × 10⁻³ and p-value = 7 × 10⁻³ ± 8 × 10⁻⁴).
