... The more massive stars have shorter lifetimes. Also, the more mass that a main sequence star has, the higher its surface temperature. Cluster D has main sequence stars with surface temperatures all the way up to 20,000 degrees and more. These are stars that do not live for very long as main sequence ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
