Abstract

(Abstract only) In this introduction we explain what a variable star is and what are its main characteristics. Variable star classification is described with images and light curves of each type, stressing that variability is—most of the time—an evolutionary stage in a star’s life. A general overview of the current status of this field of study and the always important role of the amateur astronomer—even in the automated surveys era—is presented. Finally, we take a first look at the visual observation method and give some exercises to be made during observing nights.
