Identification of birth places of high-velocity stars: CepOB2 association
We have searched high-velocity stars (runaway, walk-away, pulsars, HMXBs and LMXBs), which could have, most probably, originated in the complex CepOB2 association, i.e. in the cores (small clusters or multiple stellar systems) of it. With the trace-back motion study of them we found at least two pairs consisting of a runaway star and pulsar, which were within stellar groups in the Cep OB2 association ∼ 1.5-5.5 Myr ago.
