MATLAB Code for a Simple Model of Ejection Events on Small Asteroids

Xin Yang
Particle ejection and reaccretion of mm- to cm-sized particles onto the regolith of Bennu, is an important but until recently undiscovered mass transport process on asteroids. About 104 to 105 particles may be launched per year with 85% of them redeposited and the remainder exceeding the escape velocity. Consequently, a large number of pebble-sized fragments were relocated on Bennu’s surface, leading to global and thorough mass transport and regolith mixing. To better understand such activity...
