The stellar density distribution of the bulge is analyzed through one of itstracers. We use oxygen-rich Miras variables from the Catchpole et al. (2016)survey and OGLE-III survey as standard candles. The average age of these starsis around 9 Gyr. The population traced by Mira variables matches a boxy bulgeprediction, not an X-shaped one, because only one peak is observed in thedensity along the analyzed lines of sight, whereas the prediction of an X-shapegives two clear peaks.
