Accretion of Ornamental Equatorial Ridges on Pan, Atlas and Daphnis
Alice C. Quillen, Fatima Zaidouni, Miki Nakajima +1
We explore scenarios for the accretion of ornamental ridges on Saturn's moons Pan, Atlas, and Daphnis from material in Saturn's rings. Accretion of complex shaped ridges from ring…
Ricochets on Asteroids: Experimental study of low velocity grazing impacts into granular media
Esteban Wright, Alice Quillen, Juiliana South +6
Spin off events and impacts can eject boulders from an asteroid surface and rubble pile asteroids can accumulate from debris following a collision between large asteroids. These pr…
Excitation of Tumbling in Phobos and Deimos
Alice C. Quillen, Mckenzie Lane, Miki Nakajima +1
Mass-spring model simulations are used to investigate past spin states of a viscoelastic Phobos and Deimos. From an initially tidally locked state, we find crossing of a spin-orbit…
Boulder Stranding in Ejecta Launched by an Impact Generated Seismic Pulse
Esteban Wright, Alice C. Quillen, Juliana South +6
We consider how an impact generated seismic pulse affects the surface of an asteroid distant from the impact site. With laboratory experiments on dry polydisperse gravel mixtures,…
