Summary: This study characterizes how binarity among B-, A-, and F-type supergiants varies in environments with sub-solar metallicity. By combining multi-epoch spectroscopy with evolutionary models, the authors trace the orbital parameter distributions and predict future mass-transfer events, shedding light on how metallicity influences supergiant binary evolution.

Summary: Focusing on early B-type supergiants in the SMC, this paper surveys radial-velocity variability to derive binary fractions and period distributions. The results indicate an enhanced close-binary fraction compared to the Milky Way, suggesting that low-metallicity environments favor tighter massive-star pairs.

Summary: Investigating emission-line Oe and Be stars in metal-poor regions, this paper combines spectroscopic monitoring and photometric variability to determine companion frequencies. Results show that disk-hosting massive stars maintain high binary fractions, implying that decretion-disk formation and binarity are closely linked regardless of metallicity.
