WebApr 11, 2024 · Figure 21.1. 6 Propagating Star Formation. Star formation can move progressively through a molecular cloud. The oldest group of stars lies to the left of the diagram and has expanded because of the motions of individual stars. Eventually, the stars in the group will disperse and no longer be recognizable as a cluster. WebOct 7, 2024 · The number of typical stars that can thus be enriched is 3/ (0.3*0.01) = 1000. – ProfRob.

WebThe newly created star uses remnants of 'stardust' in the cloud nebulae to form planetary systems and then, a 'short' time later the orbiting planets (and other sized objects). So then the chronological order would be: Universe (Largest scale) => gases (very small scale) => galaxy => interstellar clouds => stars => planets (combined to form ...
WebBecause much, if not most, of the mass of a protostellar cloud must land initially on a disk, it follows that disk accretion is an important process in forming stars.
