A note on the cyclic evolution of the pulsar magnetosphere
Ioannis Contopoulos
Positive and negative pulsar breaking indices suggest that some fraction of the pulsar spindown torque undergoes a cyclic evolution. The observed strong correlation of `anomalous'…
The magnetic field topology in the reconnecting pulsar magnetosphere
Ioannis Contopoulos
We show that toroidal magnetic field annihilation in the equatorial current sheet of the pulsar magnetosphere is related to how fast poloidal magnetic field lines close as we move…
Simulations of the Poynting--Robertson Cosmic Battery in Resistive Accretion Disks
Dimitris M. Christodoulou, Ioannis Contopoulos, Demosthenes Kazanas
We describe the results of numerical "2.5--dimensional" MHD simulations of an initially unmagnetized disk model orbiting a central point--mass and responding to the continual gener…
Electromagnetic pulsar spindown
I. Contopoulos
We evaluate the result of the recent pioneering numerical simulations in Spitkovsky~2006 on the spindown of an oblique relativistic magnetic dipole rotator. Our discussion is based…
