What Happens When a Magnetar's Field Snaps?

On a magnetar a dead star that looks like a cosmic refrigerator magnet, reaching across the galaxy to drag the spoons out of your kitchen drawer, and exploding on purpose when it lets go. Neither is true. From starquakes and nuclear pasta to the March 5, 1979 burst, the reality would surprise most people who think they know this star. In this documentary, we examine what a magnetar really is: neutron star crust structure, the neutron drip line, superfluid interiors, nuclear pasta, millimetre mountains, breaking strain, the alpha-omega dynamo, magnetic dipole braking, spin-down measurement, the energy deficit that separates magnetars from ordinary pulsars, soft gamma repeaters, and the 2004 giant flare from SGR 1806-20. We also explore vacuum birefringence, photon splitting, trapped fireballs, and the 2020 fast radio burst from SGR 1935+2154. Throughout, we separate what popular culture invented from what the documented record actually shows. New here?
