Title: Detecting Quiet Massive X-ray Binaries
Abstract:
Wind accretion models of the X-ray luminosity in massive X-ray
binaries (MXRBs) predict a class of ``quiet'' MXRBs in which the stellar
wind is too weak to power a strong X-ray source. The first two
candidates systems, HD 14633 and HD 15137, were recently detected.
These O star + neutron star systems were ejected from the open cluster
NGC 654, but although they both show evidence of a past supernova within
the binary system, neither is a known X-ray emitter. These systems
provide a new opportunity to examine the ejection mechanisms responsible
for the OB runaway stars, and they can also provide key information
about the evolution of spun-up, rejuvenated massive stars.
