Except for debris, the nomenclature used is my own invention, as no work has ever been published detailing the stellar halo of this galaxy. In fact, many details are unpublished.
This image offers a good overview of the main structures on the disc and the external halo of Triangulum (M33).
The disc appears quite regular and there is an abundant presence of young stars, gases and dusts. The small bulge is dominated by an older population. The external halo presents various irregularities and thickenings that we can consider as vestiges of dwarf galaxies progressively incorporated by the greater galaxy, as foreseen by the growth models. This process is still ongoing.
