Applied Mathematics Seminars: Magnetic Field Evolution in Neutron Star Crusts

Presented by Andrew Cumming, McGill University

8 December 2017 14:00 in CM219

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.

This seminar series is the continuation of the Numerical Analysis Seminar series that ran until August 2016. This change of name reflects the broader interests of the Applied Mathematics group (note that the Mathematical and Theoretical Particle Physics group also has a seminar series).

Research Seminars by Series

The research groups in the Department of Mathematical Sciences hold several seminar series in term time. Information on date, time and location are available here.
