Physics Research Conference

Magnetic Toys in the Sky
Yuri Levin, Associate Professor and ARC Future Fellow, Monash University,

In terrestrial conditions, magnetic fields usually play second fiddle to matter. However, in space magnetic fields can play a decisive role in dynamics of many astrophysical objects. In my talk I will describe several interesting magnetic structures that do not have counterparts in terrestrial conditions:

  1. Accretion discs around supermassive black holes that are in a state of magnetic levitation
  2. Magnetically driven hurricane-like deflagration fronts that are explosively consuming oceans on rapidly spinning neutron stars.
  3. Avalanches of magnetically-induced thermoplastic failures in magnetar crusts that my be connected to the observed activity of magnetars.
