General-relativistic electromagnetic fields around a slowly rotating neutron star: time-dependent pseudo-spectral simulations

Understand

Pulsars are believed to loose their rotational kinetic energy primarily by a large amplitude low frequency electromagnetic wave which is eventually converted into particle creation, acceleration and followed by a broad band radiation spectrum.

• To date, there exist no detailed calculation of the exact spin-down luminosity with respect to the neutron star magnetic moment and spin frequency, including general-relativistic effects.
• Estimates are usually given according to the flat spacetime magnetodipole formula.
• The present paper pursue our effort to look for accurate solutions of the general-relativistic electromagnetic field around a slowly rotating magnetized neutron star.
