Evolution of the G_LMC bar length given by the outer bar radius R₁ from the Dehnen method. The cross corresponds to the isolated G_LMC model, whereas the empty and filled dots show the G_LMC + G_SMC and G_LMC + G_SMC + G_MW models, respectively. The different panels represent different sets of simulations. The vertical purple solid (dashed) lines correspond to the pericentres of the MCs of the G_LMC + G_SMC + G_MW (G_LMC + G_SMC) models. The vertical grey dashed line corresponds to the present time t = 0. The horizontal green area corresponds to the LMC bar length measured in Jiménez-Arranz et al. (2024), R_1, LMC = 2.3 kpc. For the sake of comparison, the evolution of the G_LMC bar length for the models of the fiducial set is plotted in shadowed blue lines. We only show the obtained value when Σ₂/Σ₀ > 0.2, which is the threshold used to consider that the G_LMC disc has a bar.
