Inferring binary parameters with dual-line gravitational wave detection from tight inspiraling double neutron stars
Wen-Fan Feng, Jie-Wen Chen, Tan Liu +2
Neutron star (NS) binaries can be potentially intriguing gravitational wave (GW) sources, with both high- and low-frequency radiations from the possibly aspherical individual stars…
Effects of spin-orbit coupling on gravitational waveforms from a triaxial non-aligned neutron star in a binary system
Wen-Fan Feng, Tan Liu, Jie-Wen Chen +2
Spinning neutron stars (NSs) can emit continuous gravitational waves (GWs) that carry a wealth of information about the compact object. If such a signal is detected, it will provid…
Multi-messenger observations of double neutron stars in Galactic disk with gravitational and radio waves
