- Type_II_Cepheid abstract "Type II Cepheids are variable stars which pulsate with periods typically between 1 and 50 days. Like all Cepheid variables, Type IIs exhibit a relationship between the star's luminosity and pulsation period Type II Cepheids are population II stars and are thus old, typically metal-poor, and low mass objects.Historically Type II Cepheids were called W Virginis variables, but are now divided into three subclasses based on the length of their period. Stars with periods between 1 and 4 days are of the BL Herculis subclass, 10–20 days belong to the W Viriginis subclass, and stars with periods greater than 20 days belong to the RV Tauri subclass.Type II Cepheids are important standard candles since they obey a period-luminosity relationship, although they are fainter than their classical Cepheid counterparts for a given period by about 1.6 magnitudes. Cepheid variables are used to establish the distance to the Galactic center, globular clusters, and galaxies.Longer period Type II Cepheids, which are more luminous, have been detected beyond the Local Group in the galaxies NGC 5128 and NGC 4258.".
