Igoshev, Andrei, Barrère, Paul, Raynaud, Raphaël, Guilet, Jérome, Wood, Toby, Hollerbach, Rainer  Low-field magnetars have dipolar magnetic fields of 1012-1013 G, 10-100 times weaker than the values of magnetic-field strength B ≈ 1014-1015 G used to define classical magnetars, yet they produce similar X-ray bursts and outbursts. Using direct numerical simulations of magnetothermal evolution starting from a … Read more

Igoshev, Andrei, Moraga, Nicolás A., Reisenegger, Andreas, Skene, Calum S. and Hollerbach, Rainer Magnetic field evolution in neutron star cores is not fully understood. We describe the field evolution both for one barotropic fluid as well as two collisionally coupled barotropic fluids with different density profiles using the anelastic approximation and the Navier–Stokes equations, to … Read more
