2005AJ....130.2065H Star Formation Histories of Nearby Elliptical Galaxies. I. Volume-Limited Sample Justin H. Howell Abstract. This work presents high signal-to-noise ratio spectroscopic observations of a representative sample of nearby elliptical galaxies. These observations provide a strong test of models for the formation of elliptical galaxies and their star formation histories. Combining these data with the Gonzalez data set, a volume-limited sample of 45 galaxies has been defined. Results are in agreement with previous studies: the existence of the metallicity hyperplane and the Z-plane of Trager and coworkers is confirmed, and the distribution is clearly due to physical variations in stellar population parameters and not measurement uncertainty. Trends between stellar population parameters and galaxy structural parameters suggest that angular momentum may determine the chemical abundance of a galaxy at a given mass. Key words: Galaxies: Abundances, Galaxies: Elliptical and Lenticular, cD, Galaxies: Evolution, Galaxies: Formation, Galaxies: General, Galaxies: Stellar Content
