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…

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…

Composition constraints of the TRAPPIST-1 planets from their formation

Anna C. Childs, Cody Shakespeare, David R. Rice +2

We study the formation of the TRAPPIST-1 (T1) planets starting shortly after Moon-sized bodies form just exterior to the ice line. Our model includes mass growth from pebble accret…

Exciting spiral arms in protoplanetary discs from flybys

Jeremy L. Smallwood, Chao-Chin Yang, Zhaohuan Zhu +4

Spiral arms are observed in numerous protoplanetary discs. These spiral arms can be excited by companions, either on bound or unbound orbits. We simulate a scenario where an unboun…

An Analytical Theory for the Growth from Planetesimals to Planets by Polydisperse Pebble Accretion

Wladimir Lyra, Anders Johansen, Manuel H. Cañas +1

Pebble accretion is recognized as a significant accelerator of planet formation. Yet, only formulae for single-sized (monodisperse) distribution have been derived in the literature…
