Neutron Stars as Dense Matter Laboratories
Bennett Link
Montana State University
A neutron star comprises an ultra-strong metallic crust afloat on more
than a solar mass of quantum liquid at supra-nuclear density. I will
describe how interaction of the crust with the neutron superfluid it
contains affects observed stellar rotational modes. I will demonstrate
that neutron stars with crust magnetic fields of ~10^15 G ("magnetars")
are susceptible to a thermal instability that melts the crust, leading
to rapid field evolution and release of magnetic energy. Development of
this instability could produce observed gamma-ray flares.
