Zusammenfassung:Percy highlights a "Bakers dozen"variable stars that, for various diverse reasons, have made his "all-star" list. All of them are stars that one might want to point out at their next star party or mention at next public presentation. He previously highlighted Betelgeuse (Percy 2020) and EU Del (Percy 2019) in this column. Algoly Beta Persei, is the prototype eclipsing-binary variable star. Every 2.867 days, the cool giant (KOIV) component eclipses the hot main-sequence (B8V) component, and the star fades from 2.1 to 3.4 magnitude for a few hours.
