# Could 1I/'Oumuamua be an Icy Fractal Aggregate?

Amaya Moro-Martín, 2019. _The Astrophysical Journal Letters_.

Asks whether internal structure rather than a sheet geometry could let radiation pressure produce the acceleration: a mass-fractal aggregate would need a density of about 10^-5 g per cubic centimetre, which could arise from the growth of icy dust beyond a disc's snow line. ApJL 872, L32.
