Scientific paper

We propose a 3-kilosecond ACIS-S observation toward the unidentified X-ray source AX J1226.8-6249. This object is located close to a newly discovered mid-infrared bow-shock nebula, and we find that it is highly probable that AX J1226.8-6249 is in fact a Be/X-ray runaway binary, producing a bow shock via its supersonic motion. Our proposed ACIS-S observation will enable us to estimate the position of the source with arcsecond accuracy, which will be crucial to understanding the nature of the source by determining the validity of the Be/X-ray binary hypothesis and the origin of the bow shock. If confirmed, AX J1226.8-6249 will be the first Be/X-ray binary observed with a bow shock, and only the second bow shock system (after Vela X-1) from all high-mass X-ray binaries.
