... The stars of a galaxy distribute themselves into broadly three components, viz. – disc, halo, and bulge (Figure 1). The halo is made up of an older population of stars that constitute globular clusters. Globular clusters are made up of low metallicity, dense aggregates of 50,000–100,000 stars, gravi ...
