The graph (see attached file problem 5) show the HR diagram of three real star clusters. Which cluster is the youngest?© BrainMass Inc. brainmass.com June 3, 2020, 9:04 pm ad1c9bdddf
Hello and thank you for posting your question to Brainmass.
The Hertzsprung-Russell diagram (HR - diagram) correlates between the star's color (spectral emissions) and its absolute magnitude.
The star's color in turn can be converted in turn to the star's effective surface temperature.
Plotting these stars' data creates the famous HR diagram.
Stars start their lives as ...
The solution describes briefly teh HR diagram and then explains how to determined the relative age of clusters
