Transport of dust grain particles in the accretion disk

TL;DR

This paper investigates how dust particles of various sizes move within accretion disks, considering effects like backflow and radiation pressure, to understand their influence on disk evolution and planetary composition.

Contribution

It introduces a Python tool called DUSTER for post-processing star-disk simulation data to analyze dust particle transport under different physical conditions.

Findings

Dust particle distribution varies significantly with backflow presence.

Radiation pressure impacts dust particle trajectories and distribution.

The study provides insights into dust dynamics affecting planet formation.

Abstract

Entrainment of dust particles in the flow inside and outside of the proto-planetary disk has implications for the disk evolution and composition of planets. Using quasi-stationary solutions in our star-disk simulations as a background, we add dust particles of different radii in post-processing of the results, using our Python tool DUSTER. The distribution and motion of particles in the disk is followed in the cases with and without the backflow in the disk. We also compare the results with and without the radiation pressure included in the computation.
