Action-angle variables of a binary black hole with arbitrary eccentricity, spins, and masses at 1.5 post-Newtonian order
Sashwat Tanay, Leo C. Stein, Gihyuk Cho
Accurate and efficient modeling of the dynamics of binary black holes (BBHs) is crucial to their detection through gravitational waves (GWs), with LIGO/Virgo/KAGRA, and LISA in the…

Closed-form solutions of spinning, eccentric binary black holes at 1.5 post-Newtonian order
Rickmoy Samanta, Sashwat Tanay, Leo C. Stein
The closed-form solution of the 1.5 post-Newtonian (PN) accurate binary black hole (BBH) Hamiltonian system has proven to be difficult to obtain for a long time since its introduct…
