Evidence Suggesting That 'Oumuamua Is the ~30 Myr Old Product of a Molecular Cloud
Cheng-Han Hsieh, Gregory Laughlin, Hector G. Arce, 2021. The Astrophysical Journal.
Compares the pre-encounter Galactic orbit with 50,899 F stars from Gaia DR2 and finds a dynamical age of about 35 million years, consistent with the Carina moving group; argues the implied number of such bodies is in tension with ejection from protoplanetary discs. ApJ 917, 20.
What it's used for here
The young-age kinematic argument, which supports a molecular-cloud origin.
