Top: Possible post-kick orbital properties for a NS-BH binary formed from a low-metallicity system (log  Z = 10^-3.5) that passed through a ULX phase. The period and masses shown correspond to the pre-SN orbital parameters, and the kick distribution is taken to be a Maxwellian with a 1D rms of σ = 265kms^-1, and isotropic in space. After the kick, there is a 67% chance that the binary is disrupted, and a 3.4% chance that the resulting system is compact and eccentric enough to merge in a Hubble time. Solid lines indicate final orbital parameters for fixed kick velocity v and variable angle θ formed between the kick velocity and the orbital velocity, assuming the kick to be on the orbital plane. Dashed lines indicate the same, except for a fixed θ and a variable v. The blue square at P_orb ≃ 27 days and e ≃ 0.07 corresponds to a symmetric SN (i.e. no kick). Bottom: Fraction of systems that would be disrupted or that would merge in less than a Hubble time for an isotropic fixed kick velocity.
