class redback.ejecta_relations.TwoComponentNSBH(mass_bh, mass_ns, chi_bh, lambda_ns, zeta)

Bases: object

__init__(mass_bh, mass_ns, chi_bh, lambda_ns, zeta)

Relations to connect intrinsic GW parameters to extrinsic kilonova parameters for a neutron star black hole merger with two components using relations from Kawaguchi et al. 2016. and Foucart et al. 2018

Parameters:

• 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

__call__(**kwargs)

Call self as a function.
