Fast method to simulate dynamics of two-phase medium with intense interaction between phases by smoothed particle hydrodynamics: gas-dust mixture with polydisperse particles, linear drag, one-dimensional tests
Olga Stoyanovskaya, Maxim Davydov, Maxim Arendarenko +3
To simulate the dynamics of fluid with polydisperse particles on macroscale level, one has to solve hydrodynamic equations with several relaxation terms, representing momentum tran…
Simulations of Dynamical Gas-Dust Circumstellar Disks: Going Beyond the Epstein Regime
Olga P. Stoyanovskaya, Fedor A. Okladnikov, Eduard I. Vorobyov +2
In circumstellar disks, the size of dust particles varies from submicron to several centimeters, while planetesimals have sizes of hundreds of kilometers. Therefore, various regime…
Gravitoviscous Protoplanetary Discs with a Dust Component. IV. Disc Outer Edges, Spectral Indices, and Opacity Gaps
Vitaly Akimkin, Eduard Vorobyov, Yaroslav Pavlyuchenkov +1
The crucial initial step in planet formation is the agglomeration of micron-sized dust into macroscopic aggregates. This phase is likely to happen very early during the protostella…
Monodisperse gas-solid mixtures with intense interphase interaction in two-fluid Smoothed Particle Hydrodynamics
Olga Stoyanovskaya, Tatiana Glushko, Valery Snytnikov +1
Simulations of gas-solid mixtures are used in many scientific and industrial applications. Two-Fluid Smoothed Particle Hydrodynamics (TFSPH) is an approach when gas and solids are…
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

A systematic analysis of methods for computing the trajectories of solid-phase particles applied in modern astrophysics codes designed for modeling gas-dust circumstellar disks has…
Analysis of Numerical Algorithms for Computing Rapid Momentum Transfers between the Gas and Dust in Simulations of Circumstellar Disks
O. P. Stoyanovskaya, E. I. Vorobyov, V. N. Snytnikov
Approaches used in modern numerical simulations of the dynamics of dust and gas in circumstellar disks are tested. The gas and dust are treated like interpenetrating continuous med…
The early evolution of viscous and self-gravitating circumstellar disks with a dust component
Eduard Vorobyov, Vitaly Akimkin, Olga Stoyanovskaya +2
The long-term evolution of a circumstellar disk starting from its formation and ending in the T Tauri phase was simulated numerically with the purpose of studying the evolution of…
Clump formation due to the gravitational instability of a multiphase medium in a massive protoplanetary disc
Valeriy N. Snytnikov, Olga P. Stoyanovskaya
Planetary systems form in gas-dust protoplanetary discs via the growth of solid bodies. In this paper, we show that the most intriguing stage of such growth --- namely, the transfo…
