Force-Free Foliations
Geoffrey Compère, Samuel E. Gralla, Alexandru Lupsasca
Electromagnetic field configurations with vanishing Lorentz force density are known as force-free and appear in terrestrial, space, and astrophysical plasmas. We explore a general…
Pulsar Magnetospheres: Beyond the Flat Spacetime Dipole
Samuel E. Gralla, Alexandru Lupsasca, Alexander Philippov
Most studies of the pulsar magnetosphere have assumed a pure magnetic dipole in flat spacetime. However, recent work suggests that the effects of general relativity are in fact of…
Near-horizon Kerr Magnetosphere
Samuel E. Gralla, Alexandru Lupsasca, Andrew Strominger
We exploit the near-horizon conformal symmetry of rapidly spinning black holes to determine universal properties of their magnetospheres. Analytic expressions are derived for the l…
