Nonlinear outcome of gravitational instability in an irradiated protoplanetary disc
Shigenobu Hirose, Ji-Ming Shi
Using local three dimensional radiation hydrodynamics simulations, the nonlinear outcome of gravitational instability in an irradiated protoplanetary disc is investigated in a para…
Gravito-turbulence in irradiated protoplanetary discs
Shigenobu Hirose, Ji-Ming Shi
Using radiation hydrodynamics simulations in a local stratified shearing box with realistic equations of state and opacities, we explored the outcome of self-gravity at 50 AU in a…
Dust dynamics in 2D gravito-turbulent disks
Ji-Ming Shi, Zhaohuan Zhu, James M. Stone +1
The dynamics of solid bodies in protoplanetary disks are subject to the properties of any underlying gas turbulence. Turbulence driven by disk self-gravity shows features distinct…
Hydrodynamics of Embedded Planets' First Atmospheres. II. A Rapid Recycling of Atmospheric Gas
Chris W. Ormel, Ji-Ming Shi, Rolf Kuiper
Following Paper I we investigate the properties of atmospheres that form around small protoplanets embedded in a protoplanetary disc by conducting hydrodynamical simulations. These…
Hydrodynamics of Embedded Planets' First Atmospheres. I. A Centrifugal Growth Barrier for 2D Flows
Chris W. Ormel, Rolf Kuiper, Ji-Ming Shi
In the core accretion paradigm of planet formation, gas giants only form a massive atmosphere after their progenitors exceeded a threshold mass: the critical core mass. Most (exo)p…
Gravito-Turbulent Disks in 3D: Turbulent Velocities vs. Depth
Ji-Ming Shi, Eugene Chiang
Characterizing turbulence in protoplanetary disks is crucial for understanding how they accrete and spawn planets. Recent measurements of spectral line broadening promise to diagno…
How Empty are Disk Gaps Opened by Giant Planets?
Jeffrey Fung, Ji-Ming Shi, Eugene Chiang
Gap clearing by giant planets has been proposed to explain the optically thin cavities observed in many protoplanetary disks. How much material remains in the gap determines not on…
From Dust to Planetesimals: Criteria for Gravitational Instability of Small Particles in Gas
Ji-Ming Shi, Eugene Chiang
Dust particles sediment toward the midplanes of protoplanetary disks, forming dust-rich sublayers encased in gas. What densities must the particle sublayer attain before it can fra…
