Bar (left panel) and ring (right panel) fractions for TDE host galaxies and various control samples. The bar/ring fractions for our TDE host galaxy sample, determined through visual classification, are indicated by the red bars. The gray bars represent the corresponding fractions for their matched control samples, classified using an identical visual method. These are shown for both the overall galaxy population and specifically for those within the GV. For comparison, the bar and ring fractions from the Galaxy Zoo (light green) and GALAXY CRUISE (light blue) control samples are also displayed. Overall, these results indicate that TDE host galaxies are more likely to possess bar or ring structures than their control samples, with this enhancement being more pronounced among TDE hosts located in the GV.
