Abstract
We present the Computational Relativity CoRe collaboration's public database
of gravitational waveforms from binary neutron star mergers. The database
currently contains 367 waveforms from numerical simulations that are consistent
with general relativity and that employ constraint satisfying initial data in
hydrodynamical equilibrium. It spans 164 physically distinct configuration with
different binary parameters (total binary mass, mass-ratio, initial separation,
eccentricity, and stars' spins) and simulated physics. Waveforms computed at
multiple grid resolutions and extraction radii are provided for controlling
numerical uncertainties. We also release an exemplary set of 18 hybrid
waveforms constructed with a state-of-art effective-one-body model spanning the
frequency band of advanced gravitational-wave detectors. We outline present and
future applications of the database to gravitational-wave astronomy.
