Two component NSBH model with dynamical and disk wind ejecta

Parameters:

  • time – observer frame time in days

  • redshift – redshift

  • mass_bh – mass of black hole

  • mass_2 – mass of neutron star

  • chi_bh – spin of black hole along z axis

  • lambda_ns – tidal deformability of neutron star

  • zeta – fraction of disk that gets unbound

  • vej_2 – disk wind velocity in c

  • kappa_1 – gray opacity of first component

  • kappa_2 – gracy opacity of second component

  • tf_1 – floor temperature of first component

  • tf_2 – floor temperature of second component

  • kwargs – additional keyword arguments

  • ejecta_relation – a class that relates the instrinsic parameters to the kilonova parameters default is TwoComponentNSBH

  • frequency – Required if output_format is ‘flux_density’. frequency to calculate - Must be same length as time array or a single number).

  • bands – Required if output_format is ‘magnitude’ or ‘flux’.

  • output_format – ‘flux_density’, ‘magnitude’, ‘spectra’, ‘flux’, ‘sncosmo_source’

  • lambda_array – Optional argument to set your desired wavelength array (in Angstroms) to evaluate the SED on.

  • cosmology – Cosmology to use for luminosity distance calculation. Defaults to Planck18. Must be a astropy.cosmology object.

Returns:

set by output format - ‘flux_density’, ‘magnitude’, ‘spectra’, ‘flux’, ‘sncosmo_source’
