Stellar Populations of Bulges in Galaxies with Low Surface-brightness Discs
The radial profiles of the age, metallicity and α/Fe enhancement of the stellar populations in the bulge-dominated region for a sample of eight spiral galaxies with low surface-brightness stellar discs and bulges are presented. Almost all the sample bulges are characterised by young stellar populations, solar α/Fe enhancements and metallicities
