cds-question@unistra.frgalaxiesphotometrygalaxy-classification-systemschemical-abundancesWe present the radial profiles of the H{alpha}, Mg and Fe line-strength indices for a sample of eight spiral galaxies with a low-surface-brightness stellar disc and a bulge. The correlations between the central values of the line-strength indices and velocity dispersion are consistent with those known for early-type galaxies and bulges of high-surface-brightness galaxies. The age, metallicity and {alpha}/Fe enhancement of the stellar populations in the bulge-dominated region are obtained using stellar population models with variable element abundance ratios.2012MNRAS.423..962Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/423/962CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/105/209 : Low surface brightness galaxies.
