Azimuthal Dust Polarization from Aerodynamically Aligned Grains as Evidence for the Streaming Instability in Protoplanetary Disks
Zhe-Yu Daniel Lin, Jeonghoon Lim, Jacob B. Simon +8
(Sub)millimeter dust polarization in protoplanetary disks has revealed the presence of large (~ 100 um) dust grains that are aligned along their long axis following the azimuthal d…

glitterin: Towards Replacing the Role of Lorenz-Mie Theory in Astronomy Using Neural Networks Trained on Light Scattering of Irregularly Shaped Grains
Zhe-Yu Daniel Lin, Alycia J. Weinberger, Evgenij Zubko +2
Light scattering by dust particles is often modeled assuming the dust is spherical for numerical simplicity and speed. However, real dust particles have highly irregular morphologi…

Early Grain Growth in the Young Protostellar Disk HH 212 Supported by Dust Self-Scattering Modeling
Ying-Chi Hu, Chin-Fei Lee, Zhe-Yu Daniel Lin +3
Grain growth in disks around young stars plays a crucial role in the formation of planets. Early grain growth has been suggested in the HH 212 protostellar disk by previous polariz…
