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…
The structure of young star clusters
P. P. Gladwin, S. Kitsionas, H. M. J. Boffin +1
We analyse and compare the clustering of young stars in Chamaeleon I and Taurus. We compute the mean surface-density of companion stars \bar{N} as a function of angular displacemen…
Spiral Structure in IP Peg: Confronting Theory and Observations
Takuya Matsuda, Makoto Makita, Hiroshi Yukawa +1
The first convincing piece of evidence of spiral structure in the accretion disc in IP Pegasi was found by Steeghs et al. (1997). We performed two kinds of 2D hydrodynamic simulati…
Numerical simulations of protostellar encounters III. Non-coplanar disc-disc encounters
S. J. Watkins, A. S. Bhattal, H. M. J. Boffin +2
It is expected that an average protostar will undergo at least one impulsive interaction with a neighbouring protostar whilst a large fraction of its mass is still in a massive, ex…
Numerical simulations of protostellar encounters II. Coplanar disc-disc encounters
S. J. Watkins, A. S. Bhattal, H. M. J. Boffin +2
It is expected that an average protostar will undergo at least one impulsive interaction with a neighbouring protostar whilst a large fraction of its mass is still in a massive, ex…
Numerical simulations of protostellar encounters I. Star-disc encounters
H. M. J. Boffin, S. J. Watkins, A. S. Bhattal +2
It appears that most stars are born in clusters, and that at birth most stars have circumstellar discs which are comparable in size to the separations between the stars. Interactio…
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…
Gas-cooling by dust during dynamical fragmentation
A. P. Whitworth, H. M. J. Boffin, N. Francis
We suggest that the abrupt switch, from hierarchical clustering on scales larger than 0.04 pc, to binary (and occasionally higher multiple) systems on smaller scales, which Larson…
