Morphology and Structures of Nearby Dwarf Galaxies
Published online by Cambridge University Press: 09 May 2016
Abstract
We applied GALFIT and STARLIGHT to the r-band images and spectra, respectively, of ~1,100 dwarf galaxies to analyze the structural properties and stellar populations. In most cases, single component with n = 1 ~ 1.5 well describes the luminosity distribution of dwarf galaxies. However, a large fraction of dS0, dEbc, and dEblue galaxies show sub-structures such as spiral arms and rings. There is a bimodal distributions of stellar ages in dS0 galaxies. But other sub-types of dwarf galaxies show a single peak in the stellar distributions.
