Code Development

I developed and have been maintaining a few open-source codes:

Visualizations

  • [Interactive] τ-Zcrit map for the key results from Li & Youdin, 2021, Thresholds for Particle Clumping by the Streaming Instability
  • [Video] State-of-the-art 3D simulation of planetesimal formation with hitherto the highest grid resolution and with more than 100 million dust particles from Li, Youdin, & Simon, 2019, Demographics of Planetesimals Formed by the Streaming Instability.
    Some variations of this video are available: (i) particle only, 3D; (ii) particle only, 3D, grayscale, and (iii) particle only, 2D.
  • [Video] An example N-body simulation of a six-planet system initially in a near-resonant chain, where two major merger events take place in the 100 Myr of evolution. Data is from Li, Chiang, Choksi, & Dai, 2024, The Resonant Remains of Broken Chains from Major and Minor Mergers
  • [Video] An example hydrodynamical simulation of embedded, stellar-mass binary black holes interacting with the AGN disk, in a local shearing box with seven levels of static mesh refinement, resolving the binary Hill radius by ~1000 cells -- an unparalleled high resolution. Data is from Li & Lai 2024, Hydrodynamical evolution of black-hole binaries embedded in AGN discs - III. The effects of viscosity
  • [Interactive] 3D iso-surface anmiation of an embedded binary black hole in a global AGN disk simulation, from a paper in preparation.
  • [Interactive] dust accumulation survey results from Li, Chen, & Lin 2022, Dust Accumulation near the Magnetospheric Truncation of Protoplanetary Discs around T Tauri Stars
  • [Interactive] dust accumulation survey results from Li, Chen, & Lin 2024, Dust Accumulation near the Magnetospheric Truncation of Protoplanetary Discs: II. The Effects of Dust Opacity
