A recent impact origin of Saturn's rings and mid-sized moons
Luís F. A. Teodoro, Jacob A. Kegerreis, Paul R. Estrada +5
We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn's remarkably young rings. Such an event could have been triggered a few…
Constraints on the initial mass, age and lifetime of Saturn's rings from viscous evolutions that include pollution and transport due to micrometeoroid bombardment
Paul R. Estrada, Richard. H. Durisen
The Cassini spacecraft provided key measurements during its more than twelve year mission that constrain the absolute age of Saturn's rings. These include the extrinsic micrometeor…
Large mass inflow rates in Saturn's rings due to ballistic transport and mass loading
R. H. Durisen, Paul. R. Estrada
The Cassini mission provided key measurements needed to determine the absolute age of Saturn's rings, including the extrinsic micrometeoroid flux at Saturn, the volume fraction of…
Formation of the First Planetesimals via the Streaming Instability in Globally Turbulent Protoplanetary Disks?
Paul R. Estrada, Orkan M. Umurhan
Using self-consistent models of turbulent particle growth in an evolving protoplanetary nebula of solar composition we find that recently proposed local metallicity and Stokes numb…
Global Modeling of Nebulae With Particle Growth, Drift, and Evaporation Fronts. III. Redistribution of Refractories and Volatiles
Paul R. Estrada, Jeffrey N. Cuzzi
Formation of the first planetesimals remains an unsolved problem. Growth by sticking must initiate the process, but multiple studies have revealed a series of barriers that can slo…
Global Modeling of Nebulae With Particle Growth, Drift, and Evaporation Fronts. II. The Influence of Porosity on Solids Evolution
Paul R. Estrada, Jeffrey N. Cuzzi, Orkan M. Umurhan
Incremental particle growth in turbulent protoplanetary nebulae is limited by a combination of barriers that can slow or stall growth. Moreover, particles that grow massive enough…
