Daryl ManningUsing an end-to-end model, @[email protected], @[email protected] et al. find that the parents of the first binary neutron star merger were stars of 10+ solar masses born during Cosmic Noon that interacted repeatedly, but remained bound even through two supernovae: https://www.nature.com/articles/s41550-022-01873-y?utm_campaign=natastronTWT

End-to-end study of the host galaxy and genealogy of the first binary neutron star merger - Nature Astronomy
From an end-to-end model that characterizes the host galaxy, environment and progenitors of the binary neutron star merger gravitational wave event GW170817, the preferred solution is 2 low-metallicity stars of >10 solar masses that were born during Cosmic Noon, interacted repeatedly and remained bound even through 2 supernovae.
