Simulations and software

These pages contain a repository of Surrey astrophysics simulations and community software.

Code developed by members of the Surrey astrophysics group:

  • binary_c The binary_c and binary_grid codes together form a state-of-the-art software framework for the evolution of single and binary stars, nucleosynthesis studies and stellar population calculations.

  • EMACSS (Evolve Me a Cluster of StarS) A rapid clusters evolution code developed by Poul Alexander (Cambridge) and Mark Gieles. The accompanying papers can be found here: version 1version 2version 3.

  • LIMEPY (Lowered Isothermal Model Explorer in PYthon) A python base code to solve a general class of lowered isothermal model, including Michie (1963)/King (1966)and Wilson (1975), including radial anisotropy and multi-mass systems (Gieles & Zocchi, ArXiv 1508.02120)

  • NBODY6tt An adapted version of Aarseth's NBODY6 (NBODY6 Tidal Tensor) Allows user defined external potentials to be applied to the cluster. Written by Florent Renaud (Surrey, formerly at Strassbourg and Saclay) and Mark Gieles (Surrey). Method papers can be found here and this was applied to clusters in merging galaxies and star clusters in dwarf galaxies accreting on the Milky Way.

  • Window to the Stars a graphical user interface to the popular TWIN single/binary stellar evolution code, for novices, students and professional astrophysicists. It removes the drudgery associated with the traditional approach to running the code, while maintaining the power, output quality and flexibility a modern stellar evolutionist requires. It is currently being used for cutting edge research and interactive teaching. Virtualbox image.
