dE review notes

Working title: Dwarf Elliptical Galaxies: Open Questions

Various topics:
  • Are dE and dSph the same beast?
  • Did dE form their stars rapidly? 
  • Both alpha/Fe and rotation have some bearing on this
  • Is there any evidence for delayed star-formation due to the UV background?
  • How strong is the evidence that some/most dE are stripped spirals?
  • What are the nuclei and how did they form?
