Dust Drift Timescales in Protoplanetary Disks at the Cusp of Gravitational Instability
Jonathan P. Williams, Caleb Painter, Alexa R. Anderson +1
Millimeter emitting dust grains have sizes that make them susceptible to drift in protoplanetary disks due to a difference between their orbital speed and that of the gas. The char…
