LBA observations for project V616 semester 2022APRS

Colliding-wind binaries (CWB) are unique laboratories for investigating the particle acceleration in stellar environment. Owing to the difficulties in identify CWB using traditionalradial velocity variations from optical observations, the number of confirmed CWBs is very limited. The non-thermal radio emission from the bow-shaped wind-colliding region (WCR) provide an effective method to identify the CWB system. In this proposal, we request to observe a CWB candidates WR105 using the LBA to detect and image the potential WCR, this allows us to provide strong observational constrains not only for the CWB identification but also for finding its binary companies.
