We find that the C dust grains produced in the 13 Msun SN induce fragmentation at [Fe/H] = -9. <LINK> <LINK>', 'Stars with such low iron abundances may be detected in larger surveys. The record holders are [Fe/H] &lt; -7.1 (Keller+) and a detected [Fe/H] = -6.2 (Nordlander+) by @annafrebel, @AstroRana, and collab.\n\nThese ancient stars are imprinted from the first stars in the Universe. https://t.co/FcFueT4pFZ']",20,07,553
