General-relativistic magnetar magnetospheres in 3D with physics-informed neural networks

Petros Stefanou, Arthur G. Suvorov, José A. Pons

Magnetar phenomena are likely intertwined with the location and structure of magnetospheric currents. General-relativistic effects are important in shaping the force-free equilibri…

Modelling 3D Force-Free Neutron Star Magnetospheres

Petros Stefanou, Jose A. Pons, Pablo Cerdá-Durán

Magnetars exhibit a variety of transient high-energy phenomena in the form of bursts, outbursts, and giant flares. It is a common belief that these events originate in the sudden r…

Hybrid Numerical Simulations of Pulsar Magnetospheres

Ioannis Contopoulos, Jerome Petri, Petros Stefanou

We continue our investigation of particle acceleration in the pulsar equatorial current sheet (ECS) that began with Contopoulos (2019) and Contopoulos & Stefanou (2019). Our basic…

A ring-of-fire in the pulsar magnetosphere

Ioannis Contopoulos, Petros Stefanou

Contopoulos 2019 proposed that a dissipation zone develops in the magnetosphere of young pulsars at the edge of the closed-line region beyond the light cylinder. This is necessary…
