-===== Challenge 2: Multi-mass clusters (no stellar evolution) ===== +The definition of the stellar types (KSTAR) used in the ''NBODY6'' snapshots can be found in the [[:tests:collision:mock_data:appendix|Appendix]].
- +
-Data: Snapshots of simulations with a mass function.  +
-   - N <~= $10^5$, initial half-mass radius 2.25 pc, Henon isochrone model +
-   - Initial half-mass relaxation time =~ 350 Myr +
-   - no primordial binaries +
-   - Galaxy = singular isothermal sphere with Vc = 220 kms/s +
-   - Orbit: circular orbit at RG = 4 kpc +
- +
-The $10^5$ stars were evolved with SSE (Hurley et al. 2000) to an age of 12 Gyr assuming a metallicity of [Fe/H] = -2 **before** the N-body model was run. Then an assumption was made about the retention fraction of neutron stars (NSs) and black holes (BHs). The snapshots contain all the stars within the tidal radius. +
- +
-The properties of the snapshots are: +
- +
-^ Name ^ f_retention NSs ^ f_rentention BHs ^ age ^ N(NS)_remaining ^ N(BH)_remaining ^ +
-| cluster1 | 1 | 1 | 0.25 Gyr | 613 | 171 |  +
-| cluster1 | 1 | 1 | 0.5 Gyr  | 591 | 146 |  +
-| cluster1 | 1 | 1 | 0.75 Gyr | 559 | 134 |  +
-| cluster1 | 1 | 1 | 1 Gyr    | 548 | 119 |  +
-| cluster7 | 0.1 | 0.1 | 2 Gyr | 51 | 0 |  +

-===== Challenge 3. Clusters in tidal fields with stellar evolution ===== +
-(Simulations ran and kindly made available by Holger Baumgardt)\\ +
- +
-Here we consider 2 clusters which are slightly more realistic: +
- +
-  - IC: King (1966) W_0 = 5 model, N = 131072, Kroupa (2001) mass function between 0.1-15 Msun (no black-holes). +
-  - No primordial binaries, no central black hole, circular orbit in logarithmic halo with V = 220 km/s. +
-  - Z = 0.001 +
-  - Stellar evolution and mass-loss according to Hurley et al. (2000, 2002) +
-  - Two Galactocentric radii: 8.5 kpc and 15 kpc. +
- +
- +
-Below are 2 snapshots at an age of roughly 10 Myr, 100 Myr, 1Gyr and 12 Gyr. The columns are the same as in Challenge 2. +
