∗ Previous aﬃliations where part of this work was carried out. A scalar charged particle moving in a curved background spacetime will emit a ﬁeld eﬀecting its own motion; the resolving of this resulting motion is often referred to as the self-force problem. This also serves as a toy model for the astrophysically interesting compact body binaries, Extreme Mass Ratio Inspirals, targets for the future space-based gravitational wave detector, LISA. In the modelling of such systems, a point particle…
