TITLE:	  The Milky Way in Seven Dimensions


SPEAKER:  Harshil Kamdar (Harvard)


ABSTRACT:

The clustered nature of star formation and the presence of spiral arms in our 
galaxy should produce a high degree of structure in both the kinematics and the 
chemical make-up of stars. In this talk, I will present a new dynamical model 
of the galactic disk that takes into account the clustered nature of star 
formation. This model predicts that the combined phase and chemical space is 
rich in substructure and that this structure is sensitive both to the precise 
nature of clustered star formation and the galaxy's large-scale properties. The 
model self-consistently evolves 4 billion stars over the last 5 Gyr in a 
realistic potential that includes an axisymmetric component, a bar, spiral 
arms, and giant molecular clouds. We demonstrate that the combination of 
chemical and phase space information is much more effective at identifying 
truly co-natal populations than either chemical or phase space alone. I will 
highlight a few key results from the simulations and the potential for 
harnessing the synergies between current data and our models to reveal the 
assembly history of the galaxy.
