N2 - We perform the first general relativistic force-free simulations of neutron star magnetospheres in orbit about spinning and nonspinning black holes. We find promising precursor electromagnetic emission: typical Poynting luminosities at, e.g., an orbital separation of r=6.6RNS are L EM∼6×1042(BNS,p/1013 G) 2(MNS/1.4M) 2 erg/s. The Poynting flux peaks within a broad beam of ∼40 in the azimuthal direction and within ∼60 from the orbital plane, establishing a possible lighthouse effect. Our calculations, though preliminary, preview more detailed simulations of these systems that we plan to perform in the future.
