Magneto-elastic oscillations of neutron stars: exploring different magnetic field configurations
We study magneto-elastic oscillations of highly magnetized neutron stars (magnetars) which have been proposed as an explanation for the quasi-periodic oscillations (QPOs) appearing in the decaying tail of the giant flares of soft gamma-ray repeaters (SGRs). We extend previous studies by investigating various magnetic field configurations, computing the Alfvén spectrum in each case and performin...
متن کاملDirect evidence for the onset of intruder configurations in neutron-rich Ne isotopes
Monte Carlo shell-model calculations with the modern SDPF-M interaction successfully describe neutron-rich nuclei in the vicinity of N = 20 where normal and intruder configurations coexist at low excitation energy. We report on direct experimental evidence of the population of the 3/2− intruder state in 27Ne in the knockout of a single neutron from the ground state of 28Ne. This low-lying negat...
متن کاملStationary magnetic field configurations in accretion discs around neutron stars – the role of velocity and diffusivity
We report results from calculations investigating stationary magnetic field configurations in accretion discs around magnetised neutron stars. Our strategy is to start with a very simple model and then progressively improve it providing complementary insight into results obtained with large numerical simulations. In our first model, presented here, we work in the kinetic approximation and consi...

متن کاملPost-Newtonian treatment of bar mode instability in rigidly rotating equilibrium configurations for neutron stars
In this paper we determine the onset point of secular instability for the nonaxisymmetric bar mode in rigidly rotating equilibrium configurations in the PostNewtonian approximation, in order to apply it to neutron stars. The treatment is based on a precedent Newtonian analytic energy variational method which we have extended to the Post-Newtonian case. This method, based upon Landau’s theory of...
