Constraining Nuclear Symmetry Energy with Multi-messenger Resonant Shattering Flares

Understand

Much effort is devoted to measuring the nuclear symmetry energy through neutron star (NS) and nuclear observables.

• Since matter in the NS core may be non-hadronic, observables like radii and tidal deformability may not provide reliable constraints on properties of nucleonic matter.
• We demonstrate that coincident timing of a resonant shattering flare (RSF) and gravitational wave signal during binary NS inspiral probes the crust-core transition region and provides constraints on the symmetry energy comparable to terrestrial nuclear experiments.
• We show that nuclear masses, RSFs and measurements of NS radii and tidal deformabilities constrain different density ranges of the EOS, providing complementary probes.
