We measure the projected rotational velocities of the late B-type hypervelocity stars HVS 7 and HVS 8 from high-resolution spectroscopy to be 60 ± 17 km s −1 and 260 ± 70 km s −1 . The "slow" rotation of HVS 7 is in principle consistent with having originated in a binary system, assuming a high incl...
