Spatial Age Distribution of Classical Cepheids in Spiral Galaxies: The Cases of M31 and M33

Spatial Age Distribution of Classical Cepheids in Spiral Galaxies: The Cases of M31 and M33

Classical Cepheids can be used as age indicators due to well-established period–age and period–age–color relations. G. De Somma et al. refined these relations by including a metallicity term and different mass–luminosity assumptions. In this study, we apply the period–age–metallicity relation for th...
