Question

question 16 of 29 > use the h - k diagram to arrange the star clusters from youngest to oldest.

Explanation:

In an H - K diagram, younger star clusters have more massive and hotter stars. The more massive stars evolve faster and disappear from the cluster over time. So, clusters with hotter and more luminous stars are younger. By observing the positions of the star - clusters on the diagram in terms of temperature and luminosity, we can rank them.

Answer:

Cluster β, Cluster γ, Cluster Δ, Cluster ε, Cluster Σ
