How do cepheids form?
Cepheids typically form with masses 3-30 times that of the Sun, then pass through the main sequence stage as B-class stars and, once they have burnt up the hydrogen in their core, their helium core loses stability and begins to contract and expand at regular intervals and they undergo stages of nuclear burning. Cepheids are high-mass stars in the late stages of their existence that are luminous enough to be seen by the unaided eye and easily found in the neighbouring galaxies. Since their luminosities are directly tied to their pulsation periods, astronomers only need to measure the stars’ visual magnitude to determine their distance and the distances of the galaxies where the stars are located.
