Nonlinear electrodynamics in magnetars: systematic effects on radius constraints and timing analysis
Gabriel A. Porto, Jonas P. Pereira, Eduardo Bittencourt +1
Magnetars are among the most extreme laboratories in the universe, harboring surface magnetic fields reaching ~G. At these supercritical scales, Maxwell's linear electrody…
