Blue straggler candidates in Haffner 10: testing a Gaia colour–astrometry diagnostic against data-quality systematics
While long-term radial velocity (RV) monitoring has successfully mapped blue straggler star (BSS) multiplicity in nearby, unreddened open clusters, such spectroscopic surveys are observationally prohibitive for distant (d > 2 kpc) and moderately reddened Galactic clusters. To bypass this limitation, we present a gene...
