Electromagnetic draping of merging neutron stars by Maxim Lyutikov. on Wednesday 30 November

We first derive a set of equations describing general stationary

configurations of relativistic force-free plasma, without assuming any

geometric symmetries. We then demonstrate that electromagnetic interaction of

merging neutron stars is necessarily dissipative due to the effect of

electromagnetic draping - creation of dissipative regions near the star (in the

single-magnetized case) or at the magnetospheric boundary (in the

double-magnetized case). Our results indicate that even in the single

magnetized case we expect that relativistic jets (or ``tongues'') are produced,

with correspondingly beamed emission pattern.
