The 3D pulsar magnetosphere with machine learning: first results
Ioannis Dimitropoulos, Evaggelos Chaniadakis, Ioannis Contopoulos
All numerical solutions of the pulsar magnetosphere over the past 25 years show closed-line regions that end a significant distance inside the light cylinder, and manifest thick st…
Scaling up global kinetic models of pulsar magnetospheres using a hybrid force-free-PIC numerical approach
Adrien Soudais, Benoît Cerutti, Ioannis Contopoulos
The particle-in-cell approach has proven effective at modeling neutron star and black hole magnetospheres from first principles, but global simulations are plagued with an unrealis…
A new solution of the pulsar equation
Ioannis Contopoulos, Ioannis Dimitropoulos, Dimitris Ntotsikas +1
We present the first new type of solution of the pulsar equation since 1999. In it, the whole magnetosphere is confined inside the light cylinder and an electrically charged layer…
Twisted magnetar magnetospheres
D. Ntotsikas, K. N. Gourgouliatos, I. Contopoulos +1
Magnetar magnetospheres are strongly twisted, and are able to power sudden energetic events through the rapid release of stored electromagnetic energy. In this paper, we investigat…
On the pulsar Y-point
I. Contopoulos, D. Ntotsikas, K. N. Gourgouliatos
The pulsar magnetosphere is divided into a corotating region of closed field lines surrounded by open field lines that emanate from the two poles of the star, extend to infinity an…
The Pulsar Magnetosphere with Machine Learning: Methodology
Ioannis Dimitropoulos, Ioannis Contopoulos, Vassilis Mpisketzis +1
In this study, we introduce a novel approach for deriving the solution of the ideal force-free steady-state pulsar magnetosphere in three dimensions. Our method involves partitioni…
Current closure through the neutron star crust
V. Karageorgopoulos, K. N. Gourgouliatos, I. Contopoulos
Force-free pulsar magnetospheres develop a large scale poloidal electric current circuit that flows along open magnetic field lines from the neutron star to the termination shock.…
