    The Hertzsprung-Russell Diagram and Stellar Evolution

    By Steve Quigley

    Astronomy is a unique science.  With few exceptions, everything in Astronomy is based on light, and what information we can glean from it.  The Hertzsprung-Russell diagram is an excellent example of this.  This presentation will cover the techniques, events, and people who contributed to the development of the H-R diagram.  You’ll meet Germans, Italians, Danes, Indians, English, and American scientists whose work contributed to the “final” product.  Much of the action will take place at Harvard, and there you’ll be introduced to the “Harvard Computers.” This is a very basic summary of the work that led to the H-R diagram, and the insight it gives us into the concept of Stellar Evolution—the life and death of stars…… and all from understanding the message of the photons.

    Following the main presentation, our recurring monthly presentations will include Constellation of the Month  by Terri Zittritsch
