Accretion disk dynamics, photoionized plasmas, and stellar opacities

Physics of Plasmas, 2009
We present a brief review on the atomic kinetics, modeling and interpretation of astrophysical observations, and laboratory astrophysics experiments. The emphasis is on benchmarking of opacity calculations relevant for solar structure models, photoionized plasmas research, the magnetohydrodynamic numerical simulation of accretion disk dynamics, and a ...

The development of large-scale instability in Keplerian stellar accretion disks

Astronomy Reports, 2012
Our previous studies of large-scale vortical flows arising in shear flows of stellar accretion disks with Keplerian azimuthal velocity distributions as a result of the development of small perturbations are continued. The development of large-scale instability in an accretion disk is investigated via mathematical modeling.

Formation and Evolution of Minerals in Accretion Disks and Stellar Outflows

Lecture Notes in Physics, 2003
The contribution discusses dust formation and dust processing in oxygen rich stellar outflows under non-explosive conditions, and in circumstellar discs. The main topics are calculation of solid-gas chemical equilibria, the basic concepts for calculating dust growth under non-equilibrium conditions, dust processing by annealing and solid diffusion, a ...

Alfvén Waves in Dusty Proto-Stellar Accretion Disks

2012
The magneto-rotational instability (MRI) is believed to be the mechanism responsible for a magneto-hydrodynamic (MHD) turbulence that could lead to the accretion observed in proto-stellar accretion disks. A minimum amount of ionization in this medium is necessary for the MRI to take place.
