B. Star Cluster Ages Shown below are six H-R diagrams of six separate star clusters (A-F). The location of the main sequence curve is indicated by the line. In each answer, use only the letters of the appropriate HR Diagram. Surface temperature Surface temperature Surface temperature (0) (E) Surface temperature Surface temperature Surface temperature 1) List three star clusters whose H-R diagram are not physically possible (or at least are highly unlikely). List and then briefly explain why each of these clusters is not possible. Impossible clusters: Explanation: 2) Rank the three remaining clusters from youngest to oldest. Explain why you ranked the clusters in this order. (youngest) (oldest) OR, they are all the same age Explain why you ranked the clusters in this order: Page 2 of 2 Luminosity Luminosity Luminosity luminosity 20
