Magnetorotational instability in protoplanetary discs: The effect of dust grains
We investigate the linear growth and vertical structure of the magnetorotational instability (MRI) in weakly ionised, stratified protoplanetary discs. The magnetic field is initially vertical and dust grains are assumed to be well mixed with the gas over the entire vertical dimension of the disc. For simplicity, all the grains are assumed to have the same radius (a = 0.1, 1 or 3 μm) and constit...
متن کاملMagnetorotational instability in protoplanetary discs
We investigate the linear growth and vertical structure of the magnetorotational instability (MRI) in weakly ionised, stratified accretion discs. The magnetic field is initially vertical and dust grains are assumed to have settled towards the midplane, so charges are carried by electrons and ions only. Solutions are obtained at representative radial locations from the central protostar for diff...
متن کاملGlobal MHD simulations of stratified and turbulent protoplanetary discs. II. Dust settling
Aims. The aim of this paper is to study the vertical profile of small dust particles in protoplanetary discs in which angular momentum transport is due to MHD turbulence driven by the magnetorotational instability. We consider particle sizes that range from approximately 1 micron up to a few millimeters. Methods. We use a grid–based MHD code to perform global two-fluid simulations of turbulent ...
متن کاملDust-Dust Collisional Charging and Lightning in Protoplanetary Discs
We study the role of dust-dust collisional charging in protoplanetary discs. We show that dust-dust collisional charging becomes an important process in determining the charge state of dust and gas, if there is dust enhancement and/or dust is fluffy, so that dust surface area per disc volume is locally increased. We solve the charge equilibrium equations for various disc environments and dust c...
متن کاملRadiatively heated , protoplanetary discs with dead zones . I . Dust settling and thermal structure of discs around M stars
The irradiation of protoplanetary discs by central stars is the main heating mechanism for discs, resulting in their flared geometric structure. In a series of papers, we investigate the deep links between 2D self-consistent disc structure and planetary migration in irradiated discs, focusing particularly on those around M stars. In this first paper, we analyse the thermal structure of discs th...
