Importance of eccentricities in parameter estimation of compact binary inspirals with decihertz gravitational-wave detectors
Han Gil Choi, Tao Yang, Hyung Mok Lee
During its inspiral stage, a binary black hole (BBH) produces characteristic gravitational wave (GW) signals. The waveform of the GW signals can be described by the physical parame…
