WebHenrietta Swan Leavitt, (born July 4, 1868, Lancaster, Massachusetts, U.S.—died December 12, 1921, Cambridge, Massachusetts), American astronomer known for her discovery of the relationship between period and luminosity in Cepheid variables, pulsating stars that vary regularly in brightness in periods ranging from a few days to several months. WebStars change temperature and size throughout their lifetimes, as Sal details in his videos about the life cycles of stars. When a star enters a phase during which it has the right combination of temperature and size, it will pulsate. In other words, many many stars will be Cepheids at some point during their life cycle.
