Binary population synthesis

  • Fits to single star models from detailed stellar evolution

codes

  • Modified to include effects of binary evolution
  • Simulate 1 binary < 1 sec, 106 binaries in a few hours

⇒ Tool to study populations ⇒ To investigate uncertain physics, its importance and effects

  • n populations

Four binary population synthesis codes

  • Binary_c: Izzard et al.(2004,2006,2009), Claeys et al. (subm.)
  • Brussels code: Vanbeveren et al. (1998), Mennekens et al. (2010)
  • SeBa: Portegies Zwart et al. (1996), Nelemans et al. (2001) and Toonen et al. (2012)
  • StarTrack: Belzcynski et al. (2002,2008), Ruiter et al. (2009)

Most simple comparison

  • Equalize the assumptions as far as possible, e.g.
  • Common envelope evolution
  • Initial distribution functions
  • Specifics of stable RLOF

Stellar populations

  • Single WD systems with non-degenerate companion
  • Double WD systems

  • Similarities:
  • Same evolution paths found at similar regions in mass and

separation

  • Similar birthrates of single and double WD systems
  • Differences:

→ Due to variations in the input physics

  • Initial-final mass relation
  • Stability of mass transfer
  • Survival of mass transfer
  • Helium star evolution
