Gas flow in close binary star systems
K. Oka, T. Matsuda, I. Hachisu +1
We first present a summary of our numerical work on accretion discs in close binary systems. Our recent studies on numerical simulations of the surface flow on the mass-losing star…
Application of the DSMC method to astrophysical flows
Takuya Matsuda, Hiromi Mizutani, Henri. M. J. Boffin
The Direct Simulation Monte Carlo (DSMC) method, developed originally to calculate rarefied gas dynamical problems, is applied to continuous flow including shocks assuming that the…
Three-dimensional SPH simulations of accretion discs
Henri M. J. Boffin, Kei Haraguchi, Takuya Matsuda
We discuss some 3D numerical simulations of accretion discs using the SPH method and a polytropic equation of state. We show that discs exist even for as large value of the polytro…
Application of numerical methods to modeling the stellar wind and interstellar medium interaction
Nikolai Pogorelov, Takuya Matsuda
We present a review of the application of numerical methods to solve the problem of the stellar/solar wind with the local interstellar medium. Most of approaches described are deve…
Numerical Computation of Two Dimensional Wind Accretion of Isothermal Gas
Eiji Shima, Takuya Matsuda, Ulrich Anzer +2
A new numerical algorithm for calculating isothermal wind accretion flows has been developed and is applied here to the analysis of the hydrodynamics of two-dimensional plane symme…
