Blue stragglers are stars formed via mass accretion from binary mass transfer or mergers. Determining the exact formation mechanism is a bit complicated. It requires characterisation of the blue stragglers and any possible companions. We have previously used panchromatic SED analysis to identify blue straggler companions. With the release of Gaia DR3 data, we have a lot more data across the whole sky. We found that 63 blue stragglers and related systems are classified as eclipsing binaries in
