Dust Collisions in Protoplanetary Disks: Atomic Simulations of the Surface Free Energy
L. S. Morrissey, D. S. Ebel, L. E. J. Eriksson +4
Coagulation of dust particles in protoplanetary disks is the first step on the journey to the formation of planets. The surface free energy (SFE) of the dust particles determines t…
