The GWTC-4 BNS merger rate is 28–300 Gpc^-3 yr^-1, a factor of 3.6–18 lower than the cosmological short GRB rate and 2.3–5.1 lower than Galactic DNS estimates, implying an emerging tension among neutron-star merger probes.

Binary neutron star mergers with evolving merger rates or yields are strongly preferred over constant scenarios to explain Milky Way r-process enrichment, with Bayes factors exceeding 10^20, yet remain in tension with short gamma-ray burst observations.
Simulations show hierarchical subsolar-mass mergers in collapsar disks can retain eccentricity up to e~0.1 at merger as a potential observational signature.
Population synthesis of helium star-NS systems yields DNS delay time distributions that peak between 80-250 Myr across metallicities, with 15% merging within 80 Myr and over 20% after 1 Gyr.
Kilonova-like emissions after long GRBs GRB211211A and GRB230307A are consistent with collapsar nucleosynthesis using a single weak r-process component without lanthanide-rich material.
A phenomenological nonequilibrium freeze-out model with Lagrange parameters accounts for both the universal heavy r-process abundance pattern in stars and its observed variations.
Magnetorotational r-process best explains lighter elements and CEJSN explains the third peak based on scatter and iron correlations in early metal-poor stars.
