AP Seminar: Magnetic Field Evolution in Neutron Star Crusts

Professor Andrew Cummings, of McGill University, Montreal, will be presenting a seminar on his research. All welcome to attend.

The multi-fluid nature of neutron star interiors leads to several processes that can drive magnetic field evolution despite the high electrical conductivity of the interior. Indeed, observations of neutron stars show that a significant fraction of young neutron stars are magnetically active. This includes the highly magnetized magnetars as well as high magnetic field radio pulsars. In this talk I will give an overview of the open questions regarding the magnetic fields of neutron stars and discuss recent work to understand how fields evolve in the solid crust of the star, where the non-linear Hall drift can act on short timescales and likely sources much of the observed magnetic activity.
