SUMMARY:Dissecting the Red Sequence: Star Formation Histories and Stru
 ctural Evolution of Early Type Galaxies\, Astronomy Colloquium\, Genev
 ieve Graves\, UC - Santa Cruz
DESCRIPTION:I use 16\,000 galaxy spectra from the Sloan Digital Sky Su
 rvey to probe the  varying stellar populations of early type galaxies 
 throughout the Fundamental Plane.  Not only do early type galaxies spa
 n a 2 - dimensional  family in the Fundamental Plane\, but they appear
  to span a 2-dimensional family in star formation histories.  In addit
 ion to known variations with  galaxy mass\, I present evidence that st
 ellar populations in these galaxies  are intimately linked with their 
 central dark matter fractions\, revealing  a connection between star f
 ormation history and structural evolution.  I discuss these results in
  the context of different models for galaxy evolution in a hierarchica
 l universe.
