Dark Comets? Unexpectedly Large Nongravitational Accelerations on a Sample of Small Asteroids

Darryl Z. Seligman, Davide Farnocchia, Marco Micheli et al., 2023. The Planetary Science Journal.

Reports statistically significant non-gravitational accelerations, too large for the Yarkovsky effect, on six near-Earth asteroids with no visible activity (1998 KY26 among them), and attributes them to outgassing with no dust: a class the authors name dark comets. PSJ 4, 35.
