What Distinguishes Classical Cepheids from Type II Cepheids?
š” The Answer
- Classical Cepheids are young, massive stars found in spiral arms, with periods up to 100 days.
- Type II Cepheids are older, lower-mass stars in globular clusters and galactic halos.
- Their period-luminosity relations differ, requiring separate calibrations.
- Both serve as distance indicators but for different stellar populations.
