Axisymmetric landslides on small planetary bodies
Kumar Gaurav, Ishan Sharma
We aim to understand how landslides affect the shape and rotational motion of small rubble planetary bodies. We limit ourselves to axisymmetric global landslides, and take the prim…

Coupled shape and spin evolution of small near spherical asteroids due to global regolith motion
Kumar Gaurav, Deepayan Banik, Ishan Sharma
Recent space missions have provided substantial evidence of regolith movement on the surfaces of near Earth asteroids. To investigate this phenomenon, we present a continuum-based…

Segregation on small rubble bodies due to impact-induced seismic shaking
Sohanjit Ghosh, Ishan Sharma, Deepak Dhingra
We present a framework to study regolith segregation on rubble-pile asteroids (self-gravitating granular aggregates) due to seismic shaking induced by impacts sustained during thei…
