For lab 11, I used the concept – Stellar Evolution. It is the process of showing a star changes over the course of the time. Also, it relates to the mass, ages, sizes of the stars. Also, I used the Hertzsprung-Russell (H-R) diagram concept to classify the stars and find the Main Sequence. When the stars are hotter and more luminous, they main sequence tends to follow a band going from the bottom right to the top left at the diagram. This concept can help to classify the stars, such as main sequence stars, red giant, blue giant, supergiant stars, virtually dead stars, and binary stars.
Summarize the procedure that you followed in the lab (1-2 paragraphs). Do not simply restate
