Abstract :
[en] The runaway O-type binaries HD 14633 and HD 15137 were likely ejected from the cluster of their birth by supernovae explosions in close binaries. Neither star is a known X-ray source, but they likely contain neutron stars and may be weak stellar wind accretion systems. Hence the two binaries have been classified as "quiet HMXBs". Here we present new optical spectra of these spectroscopic binaries and reassess their orbits. We also present preliminary results from recent XMM-Newton observations, intended to detect the hard power-law spectrum from accreting or quiescent neutron star companions and reveal the evolutionary history of these intriguing runaways.
