The EB Zoo: examples of eclipsing binary stars and their behaviours
In this zoo, we will display not the specimen light curves of various types of EBs (these are readily available elsewhere), but the changes in their behavior. Such changes are what most amateur observing programs aim to find and track. Specifically, here are examples of EBs whose eclipses come early or late for different reasons, and a case where the eclipses no longer happen(!).
