Describe the features of the spectrum and explain what they mean. |s the spectrum an absorption or emission spectrum? How can you tell? e Why are there black lines in the spectrum? What creates them, and what can we learn from them? e |f we were to measure the spectrum from a distant yellow star, would you expect it to look the same as this spectrum or not? Why? Photo from APODLinks to an external site. Relate the colors of the stars in the above photograph of a globular cluster to the properties of those stars. These stars are all roughly the same distance from us. e The individual stars most easily seen are on the edge of the cluster, and tend to be either orange/red or blue. e Which stars are hotter, the red or blue stars?
