Query: Concerning the occurrence of bow shocks around high-mass X-ray binaries   We investigate the occurrence of stellar bow shocks around high-mass X-ray
binaries (HMXBs) in the Galaxy. We seek to conduct a survey of HMXBs in the
mid-infrared to search for the presence of bow shocks around these objects.
Telescopes operating in the mid-infrared, such as the Spitzer Space Telescope
or Wide-field Infrared Survey Explorer (WISE), are potent tools for searching
for the stellar bow shocks. We used the available archival data from these
telescopes to search for bow shock candidates around the confirmed and
candidate HMXBs in the Galaxy. We detected extended mid-infrared structures
around several surveyed confirmed and candidate HMXBs. Two of these structures,
associated with Vela X-1 and 4U 1907+09, are genuine bow shocks that have been
studied previously. However, there are no new unambiguous bow shocks among the
rest of the objects. The paucity of bow shocks around HMXBs suggests that the
majority of these systems still reside within hot, low-density bubbles around
their parent star clusters or associations. This also implies that the
dynamical ejection of massive binaries is apparently less efficient than the
ejections caused by the supernova explosions inside a binary.
