7:00 PM Presentation "The Classification of Stars"
Have you wondered why there are different colors of the myriad of stars in the night sky? Just what is it about stellar composition that determines coloration, in addition to other characteristics? And how can astronomers and astrophysicists now so extensively analyze the makeup of these celestial bodies, many of which are thousands of light-years from Earth?
In our October meeting presentation entitled “The Classification of Stars”, Local Group member Van Webster will provide us answers to these questions and more. Van will explain how, and why, astronomers have introduced, and expanded on during the history of astronomy, increasingly sophisticated methods to categorize and classify the many billions of stars in our universe.
IVan will explain methods of classification that enable both professional and amateur astronomers alike to effectively categorize for study the objects that they observe Finally, we'll learn about a very revealing and useful graphical representation of the evolutionary tracks of many stars, called an H-R Diagram, that conveys via plots of luminosity versus temperature how stars evolve through their lifetime.
We look forward to seeing you at the meeting!
