Neutron Star - Magnetosphere Interactions

In this work we report results of the interaction of a neutron star magnetosphere in both collapsing and moving scenarios interacting with an ambient magnetic field. In recent works [1,2], it has been shown the important role and realism associated with studies of electromagnetic environments in some particular regimes, such as: ideal-MHD, force-free, and electro-vacuum. Motivated by this and their astrophysical implications for BBH and hybrid BH-NS mergers [3,4], we study the following cases: collapse of a magnetized NS, head-on collision of a BH-NS, and orbiting merger of a BH-NS. Based in the results from our simulations, we draw some relevant conclusions to the production of jets as described within the force-free formalism. \\[4pt] [1] C.Palenzuela, L.Lehner and S.Liebling, Science {\bf 329}, 927 (2010).\\[0pt] [2] C.Palenzuela, T.Garrett, et al., Phys.Rev.D {\bf 82}, 044045 (2010).\\[0pt] [3] L.Lehner, C.Palenzuela, et al., 2011.\\[0pt] [4] S.Liebling, L.Lehner, et al., Phys.Rev.D {\bf 81}, 124023 (2010).
