Underlying data for initial conditions for MOCCA star cluster models simulated in Bhat et al. 2024

Authors/Creators

Description

We provide the initial conditions for the MOCCA star cluster models simulated for the publication Bhat et al. 2024 (https://ui.adsabs.harvard.edu/abs/2024ApJ...968....2B/abstract). The CSV file contains the following information for the 108 models that were simulated as part of this study. 

  1. Model Name: The unique identifier for each simulation model. It is constructed based on the initial conditions of the model using the following format:

    Example: N500_K0_RG2_TF0.1_W05 corresponds to a simulation with 500K stars, k=0, Rg=2 kpc. TF=0.1 and W0=5.

  2. N (K): The total number of objects in the simulation, in units of thousands (K). For instance, 500 means 500,000 objects. All simulate models had 10% initial binary fraction.

  3. W0: The dimensionless central potential of the King model used to define the initial density profile of the star cluster. Values include 5, 7, etc.

  4. k: The parameter representing the Black Hole (BH) kick velocity prescription:

    • 0: Maxwellian distribution of kick velocities with σ=265  km/s (Hobbs et al., 2005).
    • 1: Reduced kick velocities based on the mass fallback prescription (Belczynski et al., 2002).
  5. Rg (kpc): The initial galactocentric distance of the cluster in kiloparsecs (kpc). Possible values are 2, 4, and 6 kpc.

  6. TF (rh/rt): The tidal filling factor, defined as the ratio of the half-mass radius to the tidal radius (rh/rt). Possible values are 0.025, 0.05, and 0.1.
