NLTE calculations indicate strontium is required to explain the onset of the 1μm feature at early times in AT2017gfo, while helium can dominate at later epochs with plausible masses.

Detection of GW190814 from the coalescence of a 23 solar-mass black hole and a 2.6 solar-mass compact object, the most unequal-mass binary yet observed with gravitational waves.
Simulations show hierarchical subsolar-mass mergers in collapsar disks can retain eccentricity up to e~0.1 at merger as a potential observational signature.
Simulations of lensed kilonovae show detection rates rise with longer minimum delay times and that AT2017gfo-like events at z=0.5 require at least 5x magnification to be detectable in LSST.
The Via Project is a planned five-year dual-hemisphere spectroscopic survey targeting over 2 million stars with 100 m/s RV stability and transient spectroscopy to r~24 using instruments on MMT and Magellan/Clay telescopes starting in 2027.
Las Cumbres achieves minute-scale GW response and GW170817-depth imaging to 250 Mpc, but galaxy-targeted follow-up is inefficient for the large O3/O4 localizations, requiring coordinated wide-field plus rapid-response strategies.
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.
New abundance measurements confirm two stars as r-II and one as borderline r-I, with r-process material older than 10 Gyr and possible links to the Thamnos structure.
Review summarizing the role of dense-matter equation of state, weak interactions, and r-process nucleosynthesis in binary neutron star mergers and their multimessenger observables.
Relativistic mean-field models provide a unified framework for describing bulk nuclear properties and the equation of state of dense neutron-rich matter in neutron stars.
