Stellar Populations in Galaxies
Published online by Cambridge University Press: 14 August 2015
Abstract
There are significant differences among old stellar systems which may partly be a function of luminosity. One such difference is the presence of nuclei in many high luminosity spiral galaxies but their absence in low luminosity irregular systems. Other differences are seen in the spectroscopic and photometric properties.
