Finding white dwarf-main sequence binaries in Gaia data with machine learning

Despite having recently officially ended its science operations in January, Gaia, one of the most prolific star explorers ever, is still providing new scientific insights. A recent paper submitted to The Astrophysical Journal and currently available on the arXiv preprint server took another look at some Gaia data to try to find a unique type of astronomical entity—white dwarf stars that are paired up in a binary with a main sequence one.
