Velocity dispersions and metallicities of box-shaped galaxies
Published online by Cambridge University Press: 07 August 2017
Abstract
Velocity dispersions and Mg2 indices were measured from CCD spectra of 13 S0 box-shaped galaxies and 5 ellipticals. Evidence for a different relation between velocity dispersion and metallicity, relative to ellipticals, was found for our S0 sample; we attribute this difference to the S0 disk component, affecting both the mean velocity dispersion and mean metallicity.
