Algol is a famous eclipsing binary type of these stars.
In a bizarre part of the history of astronomy, E.C. Pickering claimed that the study of these would particularly appeal to women. Though now associated with pulsars, the oblique rotator model was originally developed to explain Ap stars of this type. Stars that strongly display the distinguishing effect of these stars include Alpha squared Canum Venaticorum stars. Many of these are located in the (*) instability strip. Globular clusters may contain the RR Lyrae sub-type of these stars. Algol is a famous eclipsing binary type of these stars. Henrietta Leavitt worked with a special type of these stars. Edwin Hubble was able to use ones that exhibit a close relationship between their period and luminosity, as standard candles. Cepheids are a sub-type of, for 10 points, what stars that exhibit modulating luminosity over time?
