The lowest metallicity stars that still exist today represent a window into the early Universe. Studying these stars gives us a local avenue to guide our...

At present, our understanding of the formation history of the MW is limited due to the complexity of observing the imprints of accretion events and of...

1- The use and abuse of N-body codes - relaxation in spheres and disks, collective enhancement - code structure, block time steps

3- Setting up equilibrium models - choosing from a DF, Jeans equations and their limitations - disk-bulge-halo models

4- Analysis "on the fly" - code testing - made-to-measure

5- SPH basics - numerical viscosity - Kelvin-Helmholtz instabilities - other problems and their amelioration

1- The basics - overview of stellar evolution as a function of mass and metallicity - from evolutionary tracks to isochrones - quick overview of chemical...

2- More on isochrones - bolometric corrections and Teff-color relations - populating isochrones, and the IMF - simulating star clusters - simulating apparent...

4- From external galaxies to the Milky Way - basic equation of stellar statistics, computational methods - overview of available MW codes - expected populations...
