Changelog entries for this version:

1.2.0

  • vice.solar_z : dataframe
    Users may now modify their adopted solar composition.

    • vice.solar_z.epsilon_to_z_conversion : staticmethod
      New in this version.
      Converts number density relative to hydrogen to a mass fraction within
      the sun.

    • vice.elements.element.solar_z
      Now allows assignment.
      Accesing and modifying a given element's solar abundance via
      vice.solar_z is equivalent to going through the vice.elements
      module.

    • vice.elements.yield.agb
      New in this version.
      Accessing and modifying a given element's asymptotic giant branch star
      yield via vice.yields.agb.settings is equivalent to going through
      the vice.elements module.

  • vice.single_stellar_population : function
    Keyword argument "agb_model" deprecated, instead adopts the global
    asymptotic giant branch star yield.

  • vice.yields.agb.settings : dataframe
    New in this version.
    Users modify their adopted AGB star yields through a global setting,
    similar to their supernova yields, rather than specifying keyword arguments
    to functions and objects.
    Entries can be a function of progenitor stellar mass and metallicity, in
    that order, or a keyword denoting a built-in table of yields as in previous
    versions.

  • vice.yields.agb.interpolator : object
    New in this version.
    Conducts bi-linear interpolation of the asymptotic giant branch star
    yields sampled on a grid of masses and metallicities reported by a given
    study. Can be adopted as the global yield setting.

  • vice.yields.ccsne.fractional : function
    Keyword "IMF" can now be a user-defined function of stellar mass.
    New keyword arguments: "explodability", "wind", "net":

      - ``"explodability"`` : The fraction of stars which produce a core 
    collapse supernova event as a function of progenitor zero age main 
    sequence mass. 
  - ``"wind"`` : Whether or not to include stellar winds in the yield 
    calculation. 
  - ``"net"`` : Whether or not to compute a net yield, otherwise 
    computing gross yields.

  • vice.yields.ccsne.table : function
    New in this version.
    Reads in the table of progenitor masses and mass yields published in a
    given nucleosynthesis study. Will return the full isotopic breakdown if
    requested.

  • vice.yields.ccsne.engines : module
    New in this version.
    Contains popular built-in forms of black hole landscapes, both simple and
    complex. They can be adopted as the keyword argument "explodability" to
    the vice.yields.ccsne.fractional function.

    • vice.yields.ccsne.engines.engine : object
      Base class.

    • vice.yields.ccsne.engines.cutoff : engine
      Only stars up to some user-defined progenitor mass explode.

    • vice.yields.ccsne.engines.E16 : engine
      Implements the Ertl et al. (2016) black hole landscape and variations
      thereof.

    • vice.yields.ccsne.engines.S16 : module
      Module containing black hole landscapes computed in Sukhbold et al.
      (2016). The engines "N20", "S19p8", "W15", "W18", and "W20" are
      included with the same name as in the journal publication, with
      "S19p8" being an adaptation of "S19.8":

      • vice.yields.ccsne.engines.S16.N20 : engine
      • vice.yields.ccsne.engines.S16.S19p8 : engine
      • vice.yields.ccsne.engines.S16.W15 : engine
      • vice.yields.ccsne.engines.S16.W18 : engine
      • vice.yields.ccsne.engines.S16.W20 : engine

  • vice.yields.ccsne.NKT13 : module
    New in this version.
    Nomoto, Kobayashi & Tominaga (2013) core collapse supernova yield tables.

  • vice.yields.ccsne.S16 : module
    New in this version.
    Sukhbold et al. (2016) nucleosynthetic yield tables.

    • vice.yields.ccsne.S16.N20 : module
      Sukhbold et al. (2016) mass yield tables computed under the N20
      explosion engine.

    • vice.yields.ccsne.S16.W18 : module
      Sukhbold et al. (2016) mass yield tables computed under the W18
      explosion engine.

    • vice.yields.ccsne.S16.W18F : module
      Sukhbold et al. (2016) mass yield tables computed under the W18
      explosion engine, forcing explosions in the model stars which otherwise
      would not have done so.

  • vice.yields.sneia.settings : dataframe
    Now allows entries to be a function of progenitor metallicity.

  • vice.singlezone.IMF : property
    Now allows functions of stellar mass.

  • vice.singlezone.tau_star : property
    Now allows functions accepting two parameters as well as those accepting
    only one.

    Deprecated in this version.

  • vice.multizone : object
    New in this version.
    Runs multi-zone GCE simulations within a highly flexible framework.

        A stellar migration prescription based on star particles from a
        hydrodynamical simulation.
