Evidence For Turbulent Concentration In Particle-Laden Midplane Layers of Planet-Forming Disks

Orkan M. Umurhan, Debanjan Sengupta, Thomas Hartlep +2

We investigate the axisymmetric, weakly turbulent state of settled particle layers in a model of a globally laminar protoplanetary disk. We focus on conditions in which the large-s…

Aggregate Cloud Particle Effects in Exoplanet Atmospheres

Sanaz Vahidinia, Sarah E. Moran, Mark S. Marley +1

Aerosol opacity has emerged as a critical factor controlling transmission and emission spectra. We provide a simple guideline for the effects of aerosol morphology on opacity and r…

Length and Velocity Scales in Protoplanetary Disk Turbulence

Debanjan Sengupta, Jeffrey N. Cuzzi, Orkan M. Umurhan +1

In the theory of protoplanetary disk turbulence, a widely adopted \emph{ansatz}, or assumption, is that the turnover frequency of the largest turbulent eddy, , is the local Ke…

The composition of Saturn's rings

Kelly E. Miller, Gianrico Filacchione, Jeffrey Cuzzi +12

The origin and evolution of Saturn's rings is critical to understanding the Saturnian system as a whole. Here, we discuss the physical and chemical composition of the rings, as a f…

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…

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…
