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.
Magnetar population data show no statistical requirement for a distinct white-dwarf channel; a single neutron-star model suffices.
Strong magnetic fields in compact stars induce Landau quantization and magnetic-moment couplings that change the equation of state and allow additional degrees of freedom such as hyperons, Delta resonances, and quark matter.
