Description

This data release corresponds to the paper "Constraining scalar-tensor theories by neutron star-balck hole gravitational wave events" (arXiv:2105.13644). In this paper, we consider three specific models of scalar-tensor theories, including the Brans-Dicke theory (BD), the theory with scalarization phenomena proposed by Damour and Esposito-Far\`{e}se (DEF), and Screened Modified Gravity (SMG). From all 4 possible NSBH events so far, we use two of them to place the constraints. The other two are excluded in this work due to the possible unphysical deviations. Four equations of state (EoSs), sly, alf2, H4 and mpa1, are used to derive the scalar charges of neutron stars for BD and DEF. The constraints are obtained by performing the full Bayesian inference with the help of the open source software Bilby.

This dataset contains all posterior samples of the runs discussed in the paper. The models and EoSs can be read form the filenames for the runs of BD and DEF. The files of "*_half_dipole.json" correspond to the runs for constraining the dipole radiation without considering specific model parameters. All files are JSON format which is the default output format of Bilby. They are human readable and also can be processed or visualized by Bilby or PESummary conveniently.
