From a Different Star: 3I/ATLAS in the Context of the Ōtautahi-Oxford Interstellar Object Population Model
Matthew J. Hopkins, Rosemary C. Dorsey, John C. Forbes et al., 2025. The Astrophysical Journal Letters.
Places 3I in a Gaia-based population model: its velocity and radiant are as expected, its speed implies an age above 7.6 billion years and a high water fraction, and it is very unlikely to share an origin with 1I or 2I. ApJL 990, L30.
What it's used for here
3I's expected properties before they were measured; a successful prediction of its water content.
