Starlight

This book tells the amazing story of the physics of stars and starlight. While it is an in-depth study of stellar astrophysics, at the same time it requires only basic high school mathematics and physics, making it accessible to almost all amateur astronomers.

This is a book about the physics of stars and starlight. The story of starlight is truly fascinating. Astronomers analyze and interpret the light from stars using photometry and spectroscopy, then inspirational detective work combines with the laws of physics to reveal the temperatures, masses, luminosities and outer structure of these far away points of light. The laws of physics themselves enable us to journey to the very center of a star and to understand its inner structure and source of energy!

Starlight provides an in-depth study of stellar astrophysics that requires only basic high school mathematics and physics, making it accessible to all amateur astronomers. Starlight teaches amateur astronomers about the physics of stars and starlight in a friendly, easy-to-read way. The reader will take away a profoundly deeper understanding of this truly fascinating subject and find his practical observations more rewarding and fulfilling as a result.

The first in-depth book on stellar physics written specifically for amateur astronomers Shows the reader how to explore and understand physical concepts using nothing more than a pocket calculator Will enable readers to better understand professional research publications, opening up a whole world of fascinating literature to them A perfect companion to Robinson's earlier book on spectroscopy, providing readers with a deep understanding of stellar processes that will give greater meaning to their own spectroscopic observations Also ideal as a reference for astronomy/astrophysics students Includes supplementary material: sn.pub/extras

When you look up at the sky at night and see the stars, do you understand what you're looking at? What is starlight made up of, and how does it travel to us? How are stars born, and how do they die? How do we figure out how far away are the stars and how massive they are? Can we know which stars will go supernova and which will end up as white dwarfs or black holes? How long will our Sun continue to shine down on us, and how do we know its age?

There are so many questions, and in this engaging and informative book by Keith Robinson, which serves as a companion to his very popular earlier book called Spectroscopy the Key to the Stars, you will learn the basics of stellar physics and the answers to many of these questions, as well as how to figure out some of those answers for yourself.

We have come so far in our understanding of stellar light and heat. By reading this book, you, too, can understand many of the secrets of the fiery Sun that rules our Solar System and the gemlike points of light in the night sky.
