Combining three observing runs created a radio continuum emission of the full field of view. Van den Eijnden et al., 2021.
An international team of astronomy conducted radio observations of a bow shock in the X-ray binaries. The radio emission was detected by the campaign. The paper was published on arXiv.org.
A runaway high-mass X-ray binaries system consisting of an accretion star and a supergiant donor is named Vela X-1. HD 77581 launches a strong stellar wind that causes a bow shock. Only two HMXBs have experienced a bow shock.
The bow shock in Vela X-1 has only been detected by narrow-band hydrogen-alpha and by IR observations. Jacob van den Eijnden of the University of Oxford, UK, is one of the leaders of this group. The discovery was made as part of the large survey project which is aimed at performing radio observations of active, Southern X-ray binaries, cataclysmic variables, and supernovae.
Vela X-1 was seen with the telescope on three occasions. The telescope's L band receiver was used to deliver 32,768 channels and 8 second integration time per visibility point. There were 59, 61, and 60 antennas used in the array for the three observations.
The first radio bow shock to be identified around an X-ray binaries was detected by the MeerKAT observations. The peak radio density of the bow shock was calculated.
The radio emission from the Vela X-1 bow shock was discovered by J. van den Eijnden and his team.
The Science X Network will be launched in 2021.
The radio emission from the Vela X-1 bow shock was detected in November of 2021.
