A Comparative Study of the Streaming Instability: Unstratified Models with Marginally Coupled Grains
Stanley A. Baronett, Wladimir Lyra, Hossam Aly +19
The streaming instability is a leading mechanism for concentrating solids and initiating planetesimal formation in protoplanetary disks. Although numerous studies have explored its…
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…
Bridging Unstratified and Stratified Simulations of the Streaming Instability for Grains
Jeonghoon Lim, Stanley A. Baronett, Jacob B. Simon +4
The streaming instability (SI), driven by aerodynamic coupling between solids and the gas under a global radial pressure gradient, concentrates solids and facilitates planetesimal…
Magnetically Driven Turbulence in the Inner Regions of Protoplanetary Disks
David G. Rea, Jacob B. Simon, Daniel Carrera +5
Given the important role turbulence plays in the settling and growth of dust grains in protoplanetary disks, it is crucial that we determine whether these disks are turbulent and t…
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…
A solution for the density dichotomy problem of Kuiper Belt objects with multi-species streaming instability and pebble accretion
Manuel H. Cañas, Wladimir Lyra, Daniel Carrera +6
Kuiper belt objects show an unexpected trend, whereby large bodies have increasingly higher densities, up to five times greater than their smaller counterparts. Current explanation…
Turbulence in particle laden midplane layers of planet forming disks
Debanjan Sengupta, Orkan M. Umurhan
We examine the settled particle layers of planet forming disks in which the streaming instability (SI) is thought to be either weak or inactive. A suite of low-to-moderate resoluti…
Depletion of Moderately Volatile Elements by Open-System loss in the Early Solar Nebula
Debanjan Sengupta, Paul R. Estrada, Jeffrey N. Cuzzi +1
Rocky bodies of the inner solar system display a systematic depletion of the "Moderately Volatile Elements" (MVEs) that correlates with the expected condensation temperature of the…
Planet formation: The case for large efforts on the computational side
Wladimir Lyra, Thomas Haworth, Bertram Bitsch +54
Modern astronomy has finally been able to observe protoplanetary disks in reasonable resolution and detail, unveiling the processes happening during planet formation. These observe…
Dust Growth and Dynamics in Protoplanetary Nebulae: Implications for Opacity, Thermal Profile and Gravitational Instability
Debanjan Sengupta, Sarah E. Dodson-Robinson, Yasuhiro Hasegawa +1
In spite of making a small contribution to total protoplanetary disk mass, dust affects the disk temperature by controlling absorption of starlight. As grains grow from their initi…
