kilopop.population_priors.draw_disk_unbinding_efficiency(output_shape=None)[source]

Set the disk unbinding efficiency.

The unbinding efficiency is drawn from a uniform distribution over the range of values encountered in the literature of long-term GRMHD simulations of the remnant accretion disk around a neutron star merger remnant. See the paper for references to Metzger et al. 2008; Siegel & Metzger 2018; Miller et al. 2019; Fernández et al. 2019.

Parameters:

output_shape (float or tuple) – The shape/size of the efficiency values to draw.

Returns:

disk_unbinding_efficiency – The fraction of matter unbound from the accretion disk contributing to the total radiating ejecta mass of the kilonova.

Return type:

float or ndarray
