(Abstract only) Short period pulsating (SPP) variable stars represent an important stage of stellar evolution, and include the classes of W Virginis and other Cepheids, δ Scuti, and RR Lyrae, as main sequence stars begin their journey away from that path.This brief presentation will introduce these star categories, their importance, and some key features. It will also highlight the new observing section on the AAVSO’s website covering SPPs and the tools available there. Variable star observing can be done by any who wants to make observations and use them to help further science. As such, AAVSO is dedicated to advancing this area of astronomical research by welcoming all to participate in variable star astronomy.
