Turbulent Transport of Dust Particles in Protostellar Disks: The Effect of Upstream Diffusion
Tingtao Zhou, Hongping Deng, Yi-Xian Chen +1
We study the long-term radial transport of micron to mm-size grain in protostellar disks (PSDs) based on diffusion and viscosity coefficients measured from 3D global stratified-dis…
Standing solitary waves as transitions to spiral structures in gravitationally unstable accretion disks
Hongping Deng, Gordon I. Ogilvie
Astrophysical disks that are sufficiently cold and dense are linearly unstable to the formation of axisymmetric rings as a result of the disk's gravity. In practice, spiral structu…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
Nonlinear behaviour of warped discs around a central object with a quadrupole moment
Hongping Deng, Gordon Ogilvie
The nonlinear behaviour of low-viscosity warped discs is poorly understood. We verified a nonlinear bending-wave theory, in which fluid columns undergo affine transformations, with…
