The imprint of individual neutron star spins on ejecta, $r$-process nucleosynthesis, and kilonovae in binary neutron star mergers

Beyhan Karakas, Rahime Matur, David Radice +2

To leading order, the gravitational-wave (GW) signal from binary neutron stars depends on the individual spins, ${\chi }_1$ and ${\chi }_2$, only through the effective spin parameter $χ_{\rm e…
