A General Capacity Frontier of Complex Networks
Nicholas Kunz, H. Oliver Gao
From cells to cities, ecosystems to economies, complex networks exhibit peak intensities that define their empirical limit. Estimating these limits traditionally requires domain-sp…
Revisiting planetesimal formation from mm-sized grains in pressure bumps
Tabassum S Tanvir, Jacob B Simon, Daniel Carrera +1
We present evidence that the streaming instability (SI) can form planetesimals from millimeter grains inside axisymmetric pressure bumps, provided the bump is not too strongly rein…
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…
Azimuthal Dust Polarization from Aerodynamically Aligned Grains as Evidence for the Streaming Instability in Protoplanetary Disks
Zhe-Yu Daniel Lin, Jeonghoon Lim, Jacob B. Simon +8
(Sub)millimeter dust polarization in protoplanetary disks has revealed the presence of large (~ 100 um) dust grains that are aligned along their long axis following the azimuthal d…
The Streaming Instability in 3D: Conditions for Strong Clumping
Jeonghoon Lim, Jacob B. Simon, Rixin Li +3
The streaming instability (SI) is a leading mechanism for planetesimal formation, driving the aerodynamic concentration of solids in protoplanetary disks. The SI triggers strong cl…
On the Mass Budget Problem of Protoplanetary Disks: Streaming Instability and Optically Thick Emission
Daniel Godines, Wladimir Lyra, Luca Ricci +4
Statistical studies of protoplanetary disks and exoplanet populations often exhibit a "missing mass" problem, where observed dust masses in (sub-)millimeter surveys are significant…
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…
Turbulence Inhibits Planetesimal Formation in Class 0/I Disks Subject to Infall
Daniel Carrera, Abigail Davenport, Jacob B. Simon +5
There is growing evidence that planet formation begins early, within the Myr Class 0/I phase, when infall dominates disk dynamics. Our goal is to determine if Class 0/I…
Positive Feedback II: How Dust Coagulation inside Vortices Can Form Planetesimals at Low Metallicity
Daniel Carrera, Linn E. J. Eriksson, Jeonghoon Lim +2
The origin of planetesimals (100 km planet building blocks) has confounded astronomers for decades, as numerous growth barriers appear to impede their formation. In a recent…
Positive Feedback: How a Synergy Between the Streaming Instability and Dust Coagulation Forms Planetesimals
Daniel Carrera, Jeonghoon Lim, Linn E. J. Eriksson +2
One of the most important open questions in planet formation is how dust grains in a protoplanetary disk manage to overcome growth barriers and form the 100km planet building…
Probing Conditions for Strong Clumping by the Streaming Instability: Small Dust Grains and Low Dust-to-gas Density Ratio
Jeonghoon Lim, Jacob B. Simon, Rixin Li +5
The streaming instability (SI) is a leading mechanism for concentrating solid particles into regions dense enough to form planetesimals. Its efficiency in clumping particles depend…
Rapid protoplanet formation in vortices: three-dimensional local simulations with selfgravity
Wladimir Lyra, Chao-Chin Yang, Jacob B. Simon +2
Disk vortices, seen in numerical simulations of protoplanetary disks and found observationally in ALMA and VLA images of these objects, are promising sites for planet formation giv…
The Limited Role of the Streaming Instability During Moon and Exomoon Formation
Miki Nakajima, Jeremy Atkins, Jacob B. Simon +1
It is generally accepted that the Moon accreted from the disk formed by an impact between the proto-Earth and impactor, but its details are highly debated. Some models suggest that…
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…
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…
