How loud are neutron star mergers?

Bernuzzi, Sebastiano; Radice, David; Ott, Christian D.; Roberts, Luke F.; Mösta, Philipp; Galeazzi, Filippo

We release neutron star merger waveforms computed using fully general relativistic simulations of equal and unequal-mass binaries drawn from the galactic population. The simulations employ finite-temperature microphysical equations of state (LS220, DD2, and SFHo) and neutrino cooling. Please, see

for details.

Each tarball refers to a simulation and contains

• Curvature multipolar waveform \(\psi^{(4)}_{\ell m}\)
• Metric multipolar waveform \(h_{\ell m}\)
• Radiated energy and angular momentum

where

• \(t\) simulation time
• \(u\) retarded time
• \(M\) binary mass
• \(\omega_{\ell m}\) wave frequency
• \(A_{\ell m}\) wave amplitude
• \(\phi_{\ell m}\) wave phase
• \(E_\text{GW}\) radiated energy
• \(J_\text{GW}\) radiated angular momentum
• \(E_b\) binary energy
• \(j\) binary specific angular momentum
