Metallicity Gradient And The Hybrid Formation Scenario For Early-Type Galaxies

Ricardo L. C. Ogando, Marcio A. G. Maia, Cristina Chiappini +3

We present radial gradients of the Lick index Mg2 for 40 early-type galaxies. In plots of Grad(Mg2) versus mass indicators, such as log(sigma), the lower boundary of the points dis…
