Development and application of fast methods for computing momentum transfer between gas and dust in supercomputer simulation of planet formation
Olga P. Stoyanovskaya, Vitaly V. Akimkin, Eduard I. Vorobyov +4
Circumstellar discs, from which planetary systems are formed, consist of gas, dust and solids. Simulations of self-consistent dynamics of gas, dust and solids in circumstellar disc…

Two-Fluid Dusty Gas in Smoothed Particle Hydrodynamics: Fast and Implicit Algorithm for Stiff Linear Drag
Olga P. Stoyanovskaya, Tatiana A. Glushko, Nikolay V. Snytnikov +1
Simulation of the dynamics of dust-gas circumstellar discs is crucial in understanding the mechanisms of planet formation. The dynamics of small grains in the disc is stiffly coupl…

Modeling Circumstellar Disc Fragmentation and Episodic Protostellar Accretion with Smoothed Particle Hydrodynamics in Cell
Olga P. Stoyanovskaya, Nikolay V. Snytnikov, Valeriy N. Snytnikov
We discuss the ability of the smoothed particle hydrodynamics (SPH) method combined with a grid-based solver for the Poisson equation to model mass accretion onto protostars in gra…
