Equatorial twist geometry in the magnetar magnetosphere allows resonant Compton upscattering to reproduce the hard X-ray spectrum of 4U 0142+61 with optical depth limits from resonant cooling.
Force-free simulations confirm that fast magnetosonic waves undergo efficient parametric decay into secondary FMS and Alfvén waves, producing a broad spectrum and continued energy drain even after equipartition.
