SUMMARY:Cores\, anisotrophy and (complex) rotation: the (Classical) dwarf Spheroidals\, Other...\, Nicola Amorisco\, University of Copenhagen
DESCRIPTION:<br>
<br>
The presence of multiple stellar populations in dwarf Spheroidals has proved to be the key to advancing our understanding of their dynamical state\, dark matter content\, and evolutionary history. Chemo-dynamical methods use both metallicity and kinematical information from discrete spectroscopic samples to identify and disentangle any distinct sub-populations. These are then fed to dynamical analyses\, which greatly benefit from the independent constraints enforced by different sub-populations. I'll review some recent results on the subject and report on the evidence for a large dark matter core in both the Sculptor and Fornax dwarf Spheroidals\, on an attempt to characterize directly the orbital structure of these systems\, and on the detection of a complex chemo-rotational pattern in the Fornax dwarf.
