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.

An analytic sky-motion formula applied to synthetic interstellar object populations indicates that high velocities, particularly for dim objects, may cause many to go undetected, implying a larger galactic population than currently observed.
The paper estimates 3I/ATLAS lost 1.05-6.56 meters of surface material (0.10-1.13% of its mass, or 10^9-10^10 kg) during its solar system passage based on observed production rates.
