NovaMoon: A Strategic Lunar Reference Station for Positioning, Timing, and Largely Enhanced Science in the Earth-Moon System
Serena Molli, Agnès Fienga, Pascale Defraigne +82
The renewed interest in lunar exploration and the development of future lunar communication and navigation services highlight the need for a precise, stable, and interoperable geod…
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…
Perturbative black-hole and horizon solutions in gravity with explicit spacetime-symmetry breaking
Samy Aoulad Lafkih, Nils A. Nilsson, Marie-Christine Angonin +1
In this paper, we present static and spherically symmetric vacuum solutions to the mass-dimension action of an effective-field theory, choosing the diffeomorphism symmetr…
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…
Hamiltonian normal forms for the post-Newtonian binary problem
Christopher Aykroyd, Adrien Bourgoin, Christophe Le Poncin-Lafitte
We revisit the dynamics of the post-Newtonian (PN) two-body problem for two inspiraling compact bodies. Starting from a matter-only reduced Hamiltonian, we present an adapted frame…
