  • Send a mail to ahwkuepper(at)gmail.com with "McLuster Mailing List" as subject to receive announcements of critical updates and bug fixes.


Features

  • set up clusters for Nbody6, Nbody4 or simply generate a table of stars
  • choose output in Nbody units or in astrophysical units
  • specify either total number of stars or total cluster mass
  • choose one of the following density profiles:
    • Plummer (1911)
    • King (1966)
    • mass-segregated Subr
    • mass-segregated Kroupa & Baumgardt (2007)
    • Elson, Fall & Freeman (1987)
    • NEW! Nuker (Lauer et al. 1995)
    • homogeneous density
  • specify degree of mass segregation for any profile, from unsegregated to completely segregated
  • specify degree of fractality for any profile, from smooth to completely fractal
  • determine half-mass radius according to Marks & Kroupa (2012)
  • specify the cluster orbit in one of the following tidal fields:
    • near-field approximation
    • point-mass galaxy
    • full galactic potential consisting of bulge, disk and logarithmic halo
  • specify an external gas potential for Nbody6
  • choose stellar mass function between
    • single-mass
    • Kroupa (2001) two-part power-law IMF
    • user-defined multi-power-law IMF
    • Kroupa (2001) IMF with optimal sampling (Kroupa et al. 2011)
    • L3 IMF (Maschberger 2012)
  • set up evolved stellar populations using SSE (Hurley, Pols & Tout 2000)
  • determine maximum stellar mass according to Weidner & Kroupa (2006) relation
  • determine maximum stellar mass for old, evolved populations using the Prantzos (2007) relation
  • specify metallicity either as Z or as [Fe/H]
  • specify either binary fraction or number of binaries
  • choose random pairing or ordered pairing for O and B stars
  • choose between different semi-major axis distributions:
    • flat in a given interval
    • determined using the Kroupa (1995) period distribution
    • determined using the Duquennoy & Mayor (1991) period distribution
    • NEW! determined using the Sana & Evans (2011) period distribution (for high-mass binaries)
  • apply Kroupa (1995) eigenevolution to short-period binaries
  • NEW! use Sana & Evans (2011) eccentricity distribution for high-mass binaries
  • evolve binaries using BSE (Hurley, Tout & Pols 2002)
  • OpenMP multi-core usage for high performance
