For the analysis of gravitational-wave signals, fast and accurategravitational-waveform models are required. These enable us to obtaininformation on the system properties from compact binary mergers. In thisarticle, we introduce the NRTidalv3 model, which contains a closed-formexpression that describes tidal effects, focusing on the description of binaryneutron star systems. The model improves upon previous versions by employing alarger set of numerical-relativity data for its calibration, by includinghigh-mass ratio systems covering also a wider range of equations of state. Italso takes into account dynamical tidal effects and the known post-Newtonianmass-ratio dependence of individual calibration parameters. We implemented themodel in the publicly available LALSuite software library by augmentingdifferent binary black hole waveform models (IMRPhenomD, IMRPhenomX, andSEOBNRv5_ROM). We test the validity of NRTidalv3 by comparing it withnumerical-relativity waveforms, as well as other tidal models. Finally, weperform parameter estimation for GW170817 and GW190425 with the new tidalapproximant and find overall consistent results with respect to previousstudies.
