TLDR
In this article, the Schmidt number (ratio of gas to particle diusivity) is shown to rise quadratically, not linearly, with stopping time, and the particle layer becomes thinner with the strength of turbulent diusion held xed.About:

Rapid growth of gas-giant cores by pebble accretion
TL;DR: In this article, the authors measured the accretion rate onto seed masses ranging from a large planetesimal to a fully grown 10-Earth-mass core and test different particle sizes, concluding that pebble accretion can resolve the long-standing core accretion timescale conflict.

A simple model for the evolution of the dust population in protoplanetary disks
TL;DR: In this paper, a simple model that follows the upper end of the dust size distribution and the evolution of the surface density profile was developed to derive simple equations that explain the global evolution and the upper limit of the grain size distribution, which can be used for further modeling or for interpreting of observational data.
Journal ArticleDOI
Gas- and dust evolution in protoplanetary disks
TL;DR: In this paper, the authors introduce a new model similar to Brauer et al. (2008, A&A, 480, 859) in which they include the time-dependent viscous evolution of the gas disk, and in which more advanced input physics and numerical integration methods are implemented.

The effect of gas drag on the growth of protoplanets. Analytical expressions for the accretion of small bodies in laminar disks
Chris W. Ormel,Hubert Klahr +1 more
TL;DR: In this paper, the effects of gas drag on the impact radii and the accretion rates of these particles were investigated, and a laminar disk characterized by a smooth pressure gradient that causes particles to drift in radially.

Dynamics of Protoplanetary Disks
TL;DR: A review of the theory of protoplanetary disk evolution and its connection to observations can be found in this article, where the importance of these processes depends upon the initial mass, size, and magnetization of the disk, and subsequently on its opacity, ionization state, and external irradiation.
