Post-Newtonian expansion of fluxes from a scalar charge on an inclined-spherical orbit about a Kerr black hole
Jezreel C. Castillo, Charles R. Evans, Chris Kavanagh +3
Efforts are underway to accurately model extreme-mass-ratio inspirals for binaries with a spinning (Kerr) primary. At lowest order the adiabatic evolution depends on the radiation…

Post-Newtonian expansion of gravitational energy and angular momentum fluxes: inclined spherical orbits about a Kerr black hole
Jezreel C. Castillo, Charles R. Evans, Chris Kavanagh +3
We present analytical expressions for the fluxes of energy and angular momentum from a point mass on an inclined spherical orbit about a Kerr black hole. The expressions are obtain…

Self-force on a scalar charge in a circular orbit about a Reissner-Nordström black hole
Jezreel Castillo, Ian Vega, Barry Wardell
Motivated by applications to the study of self-force effects in scalar-tensor theories of gravity, we calculate the self-force exerted on a scalar charge in a circular orbit about…
