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.
