Understanding the formation and evolution of early-type, spheroid-dominated galaxies is an open question within the context of the hierarchical clustering scenario, particularly, in low-density environments. We study the main structural, dynamical, and stellar population properties and assembly histories of field spheroid-dominated galaxies formed in a ΛCDM scenario to assess to what extend they are consistent with observations. We selected spheroid-dominated systems from a ΛCDM simulation that includes star formation, chemical evolution and Supernova feedback. that are dominated by the spheroid component. We estimate the fundamental relations of ellipticals and then compare with current observations, for the subsample of more massive objects.
