  • Figure 1. Distribution [6] of star populations in the Milky Way, showing how Population II stars essentially form a halo around the disk of the Milky Way where the stars in Population I are concentrated
  • Figure 2. Assumed creation of stars. The first stars start as hypothetical, metal-free Population III stars after the big bang, which then within a few hundred million years become supernovae and seed the interstellar space with sufficient heavy elements to produce Population II stars. These stars then in turn become supernovae and finally produce the material for Population I stars, which eventually may form a supermassive black hole in the galactic centre
  • Figure 3. Possible post-population-III creation of stars. Relativistic proton jets from the supermassive black hole in the galactic centre are thermalized and form globular clusters of Population II stars, the material of which after supernova explosions ends up as Population I stars in the galactic disc, and then eventually gets drawn back into the central black hole in the galactic centre, from which it again may be emitted as pristine hydrogen in the form of relativistic jets, etc
