The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Redistribution of particles across the nucleus of comet 67P/Churyumov-Gerasimenko (2015, background): “Micrometeoroid impact has been proposed, but found to be insufficient in the case of Eros (Colwell et al. 2005).”
ACTIVITY IN GEMINID PARENT (3200) PHAETHON (2010, background): “Even neglecting centripetal effects from its rapid rotation, the gravity on Phaethon is ∼3 times smaller than on Eros and ∼700 times smaller than on the Moon; the dynamical effects of electrostatic charging should be proportionally greater.”
Simulations of the photoelectron sheath and dust levitation on the lunar surface (2010, unknown): “There are typically two points in the photoelectron sheath at which this condition is satisfied [Nitter et al., 1998;Robertson et al., 2003; Colwell et al., 2005 ].”
Scaling forces to asteroid surfaces: The role of cohesion (2010, background): “Hypothesized mechanisms for spontaneous dust levitation have relied on enhancements to the nominal charging environment to generate sufficient charge or electric field to move particles off of an asteroid’s surface (Lee, 1996; Colwell et al., 2005).”
The global effects of impact-induced seismic activity on fractured asteroid surface morphology (2005, background): “These features all lend support to electrostatic dust levitation (Lee, 1996; Colwell et al., 2005) as the mechanism for the formation of ponded deposits on Eros, as originally suggested in Robinson et al. (2001).”
