On the stability of self-gravitating protoplanetary discs
W. K. M. Rice, P. J. Armitage, I. A. Bonnell +1
It has already been shown, using a local model, that accretion discs with cooling times t_cool <= 3 Omega^-1 fragment into gravitationally bound objects, while those with cooling t…
Interactions of High and Low-Mass Planets with Protoplanetary Disks
Stephen H. Lubow, Matthew R. Bate, Gordon I. Ogilvie
We present three-dimensional numerical simulations of the interaction of a circular-orbit planet with a protoplanetary disk. We calculate the flow pattern, the accretion rate, and…
Recent Advances in Binary Star Formation Using SPH
Matthew R. Bate
We review recent advances in the study of binary star formation that have been made using the smoothed particle hydrodynamics (SPH) technique. We discuss the importance of ensuring…
Fragmentation of Molecular Clouds: The Initial Phase of a Stellar Cluster
Ralf S. Klessen, Andreas Burkert
Using smoothed particle hydrodynamics in combination with the special-purpose hardware device GRAPE, we follow the fragmentation process and dynamical evolution in the interior of…
