Nonconservative Lie series: post-Newtonian binary dynamics at 2.5PN
Christopher Aykroyd, Adrien Bourgoin, Christophe Le Poncin-Lafitte
We present a fully analytical solution to the dynamics of the non-spinning 2.5 post-Newtonian binary problem, accounting for both the long-term (secular) and short-term (oscillator…
Hamiltonian treatment of non-conservative systems
Christopher Aykroyd, Adrien Bourgoin, Christophe Le Poncin-Lafitte
We present a novel extension of Hamiltonian mechanics to nonconservative systems built upon the Schwinger-Keldysh-Galley double-variable action principle. Departing from Galley's i…
Gravitational-wave generation in the presence of Lorentz invariance violation
Samy Aoulad Lafkih, Marie-Christine Angonin, Christophe Le Poncin-Lafitte +1
We solve the wave equation for gravitational waves emitted by compact objects systems using the Multipolar Post-Minkowskian (MPM) method, and in the presence of Lorentz invariance…
