Stellar Dynamics of Dense Stellar Systems
Stellar dynamics is almost unreasonably well suited for an implementation in terms of special-purpose hardware. Unlike the case of molecular dynamics, stellar dynamics deals exclusively with a long-range force, gravity, which leads to a computational cost scaling as the square of the number of stars involved. While special tricks can lead to a reduction of this cost from ∼ N2 to ∼ N logN in the...
متن کاملThe Stellar Dynamics Toolbox
NEMO is a toolbox for users and programmers with which a wide range of experimental situations can be constructed, dynamically evolved, and analyzed. Primarily geared towards stellar dynamics, NEMO is by no means restricted to it. Great importance has been given to making the package extendible and to exibly import and export data. NEMO has been implemented within, and integrated into, the UNIX...
متن کاملThe Stellar Dynamics of !
The stellar dynamics of ! Centauri are inferred from the radial velocities of 469 stars measured with CORAVEL (Mayor et al. 1997). Rather than t the data to a family of models, we generate estimates of all dynamical functions nonparametrically, by direct operation on the data. The cluster is assumed to be oblate and edge-on but mass is not assumed to follow light. The mean motions are consisten...
متن کاملDynamics of Stellar Collisions
I compare gas-dynamical and stellar-dynamical models of collisions. These two models have distinctly different physics; for example , shocks introduce irreversibility in gas systems, while stellar systems evolve in a completely reversible fashion. Nonetheless, both models yield broadly similar results, suggesting that analogies between gas and stellar dynamics have some heuristic validity even ...
متن کاملDynamics of Triaxial Stellar Systems
Recent work on the dynamics of triaxial stellar systems is reviewed. The motion of boxlike orbits in realistic triaxial potentials is generically stochastic. The degree to which the stochasticity manifests itself in the dynamics depends on the chaotic mixing timescale, which is a small multiple of the crossing time in triaxial models with steep cusps or massive central singularities. Low-lumino...
