Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
No stellar flybys within the past 10 Myr and 500 pc in Gaia DR3 explain the present trajectory of 3I/ATLAS, which matches thin-disk kinematics despite its high peculiar velocity.
