STELLAR FORMATION AND EVOLUTION
... To be able to understand the life cycle of a star, you need a good understanding of the Hertzsprung-Russell Diagram. In 1905, two astronomers, Einar Hertzsprung and Henry Norris Russell, independently plotted the temperature of a star versus the brightness of the star. They did this with a large num ...
