kilopop.mappings.compute_secular_ejecta_mass(total_binary_mass, threshold_mass, disk_unbinding_efficiency)[source]

Compute the total secular ejecta mass.

This computes the contribution to the total ejecta mass from secular processes following the series of equations referenced in Setzer et al. 2022.

Parameters:

  • total_binary_mass (float or array) – The total mass [solar masses] of the neutron star binary.

  • threshold_mass (float or array) – The mass threshold [solar mass] for prompt collpase after merger.

  • disk_unbinding_efficiency (float or array) – The percentage of matter unbound from the remnant disk contributing to the radiating ejecta.

Returns:

secular_ejecta_mass – The total mass coming from secular processes, post-merger, to add to the total mass comprising the kilonova ejecta.

Return type:

float or array
