Euclid's near-infrared filters can separate first- and second-generation M-dwarfs in globular clusters; in NGC 6397, about 30% of M-dwarfs are first-population and the second population is oxygen-depleted by about 0.3 dex.

Exploring Multiple Stellar Populations in Globular Clusters with Euclid: A Theoretical Overview and Insights from NGC 6397
Euclid's near-infrared filters can separate first- and second-generation M-dwarfs in globular clusters; in NGC 6397, about 30% of M-dwarfs are first-population and the second population is oxygen-depleted by about 0.3 dex.
