# The Interstellar Object 'Oumuamua as a Fractal Dust Aggregate

Eirik G. Flekkøy, Jane X. Luu, Renaud Toussaint, 2019. _The Astrophysical Journal Letters_.

Reports an apparent decrease in rotation period and shows that the YORP effect could produce it if the body is a fractal aggregate with a density of about 10^-2 kg per cubic metre, and that such a structure could survive rotation and tides. ApJL 885, L41.
