Model Description
Milky Way-like N-body models simulated with the parallel GPU tree code Bonsai. Each of the three models consists of a dark matter halo, a classical bulge, and a stellar disk, represented by equal-mass particles of ~170M⊙. The basic dynamical properties of the models are summarized in the following table.
| Model | Σ8 kpc (M⊙ kpc-2) |
σR,8 kpc (km s-1) |
σz,8 kpc (km s-1) |
Vc, 8 kpc (km s-1) |
Ωb, 8 kpc (km s-1 kpc-1) |
RCR (kpc) |
ROLR (kpc) |
RILR (kpc) |
|---|---|---|---|---|---|---|---|---|
| MWaB | 45.1 | 36.9 | 14.6 | 241 | 46 | 4.7 | 9.1 | 1.7 |
| MWbB | 51.3 | 41.2 | 15.8 | 230 | 38 | 5.6 | 10.1 | 1.9 |
| MWcB | 51.9 | 43.6 | 16.3 | 228 | 40 | 5.2 | 9.8 | 1.9 |
