Particle clustering in turbulence: Prediction of spatial and statistical properties with deep learning

1 code implementation5 Oct 2022 Yan-Mong Chan, Natascha Manger, Yin Li, Chao-Chin Yang, Zhaohuan Zhu, Philip J. Armitage, Shirley Ho

The simulation data are used to train a U-Net deep learning model to predict gridded three-dimensional representations of the particle density and velocity fields, given as input the corresponding fluid fields.

PGNets: Planet mass prediction using convolutional neural networks for radio continuum observations of protoplanetary disks

1 code implementation30 Nov 2021 Shangjia Zhang, Zhaohuan Zhu, Mingon Kang

We provide programs for PGNets and the traditional fitting method from Zhang et al. (2018), and discuss each method's advantages and disadvantages.

Particle Dynamics in 3D Self-gravitating Disks II: Strong Gas Accretion and Thin Dust Disks

no code implementations6 Jan 2021 Hans Baehr, Zhaohuan Zhu

Observations suggest that protoplanetary disks have moderate accretion rates onto the central young star, especially at early stages (e. g. HL Tau), indicating moderate disk turbulence.

The ALMA Early Science view of FUor/EXor objects. I. Through the looking-glass of V2775 Ori

no code implementations2 Nov 2016 Alice Zurlo, Lucas A. Cieza, Jonathan P. Williams, Hector Canovas, Sebastian Perez, Antonio Hales, Koraljka Mužić, David A. Principe, Dary Ruíz-Rodríguez, John Tobin, Yichen Zhang, Zhaohuan Zhu, Simon Casassus, Jose L. Prieto

We report the detection of a marginally resolved circumstellar disc in the ALMA continuum with an integrated flux of $106 \pm 2$ mJy, characteristic radius of $\sim$ 30 au, inclination of $14. 0^{+7. 8}_{-14. 5}$ deg, and is oriented nearly face-on with respect to the plane of the sky.
