# Origin and evolution of NiI and FeI in the coma of the interstellar comet 3I/ATLAS throughout its trajectory

Damien Hutsemékers, Jean Manfroid, Cyrielle Opitom, 2026. _arXiv_.

Post-perihelion UVES: metals higher and declining more slowly outbound; carbonyl sublimation from cm depths; transient 100-140 K heat source (amorphous-crystalline transition?) for early Ni excess.
