Inferring neutron-star Love-Q relations from gravitational waves in the hierarchical Bayesian framework

Jinwen Deng, Lijing Shao, Yiming Dong, Zhihao Zheng, Ziming Wang

A linear relation in log space between tidal deformability and quadrupole moment describes the neutron-star Love-Q relation well enough for next-generation gravitational wave detectors.

Claims

C1strongest claim

A linear relation between lnΛ and lnQ is practically sufficient to describe the Love-Q relation with the precision expected from next-generation GW detectors; the characteristic length in dynamical Chern-Simons gravity can be constrained to 10 km or less.

C2weakest assumption

The simulated gravitational wave signals and noise properties accurately represent what real detectors will observe, and the selection of the 20 highest-SNR events with highest NS spins does not introduce bias into the recovered relation parameters.

C3one line summary

Hierarchical Bayesian inference on 20 high-SNR simulated binary neutron star events shows a linear lnΛ-lnQ relation suffices and constrains dynamical Chern-Simons gravity length scale to ≤10 km.
