Cepheid variable: A Cepheid variable (/ˈsɛfi.ɪd, ˈsiːfi-/) is a type of star that pulsates radially, varying in both diameter and temperature and producing changes in brightness with a well-defined stable period and amplitude. A strong direct relationship between a Cepheid ... (Type of variable star that pulsates radially) [100%] 2022-09-27 [Cepheid variables] [Astrometry]...
Beta Cephei variable: Beta Cephei variables, also known as Beta Canis Majoris stars, are variable stars that exhibit small rapid variations in their brightness due to pulsations of the stars' surfaces, thought due to the unusual properties of iron at temperatures of 200 ...
