Description
A variable star is one whose brightness as seen from Earth fluctuates. This variation may be caused by a change in the quantity or wavelength of the emitted light or by something partly blocking the light.
Discovering a previous unreported variable star would be the highlight of many amateur astronomers' time in the hobby! Intrinsic variables are stars whose luminosity actually changes, while extrinsic variables are those whose apparent changes in brightness are due to changes in the amount of their light that can reach the observer.
This book explores the fascinating world of variable stars, providing an introduction to these intriguing celestial objects and what they can tell us about the universe. With clear explanations and concise information, it's a valuable resource for anyone interested in astronomy or simply looking to learn more about the night sky.
