Quote from David Berns on June 16, 2025, 2:11 pmFellow stargazers - In this article, we will take a relatively “Deep Dive” into a fundamental tool of astrophysics. This tool graphically represents the relationship between the luminosity (intrinsic brightness) of stars and their surface temperature (or spectral type) -The Hertzsprung-Russell Diagram.
It is named after Ejnar Hertzsprung and Henry Norris Russell, who independently developed versions of the diagram in the early 20th century.
I hope you find some value in it.
Remember, the universe is yours to explore; let’s explore it together.
