A Maximum Stellar Surface Density in Dense Stellar Systems
We compile observations of the surface mass density profiles of dense stellar systems, including globular clusters in the Milky Way and nearby galaxies, massive star clusters in nearby starbursts, nuclear star clusters in dwarf spheroidals and late-type disks, ultra-compact dwarfs, and galaxy spheroids spanning the range from low-mass, “cusp” bulges and ellipticals to massive “core” ellipticals...
متن کاملStellar 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 کاملModeling Dense Stellar Systems: Background
I provide some background about recent efforts made in modeling dense stellar systems, within the context of the MODEST initiative. During the last four years, we have seen more than fifteen MODEST workshops, with an attendance between twenty and a hundred participants, and topics ranging from very specialized discussions to rather general overviews. 1. Dense Stellar Systems The study of star c...
متن کاملThe Starlab Environment for Dense Stellar Systems
Traditionally, a simulation of a dense stellar system required choosing an initial model, running an integrator, and analyzing the output. Almost all of the effort went into writing a clever integrator that could handle binaries, triples and encounters between various multiple systems efficiently. Recently, the scope and complexity of these simulations has increased dramatically, for three reas...
متن کاملSpiegel - A Visualization System for Dense Stellar Systems
The extended abstract describes a distributed visualization system called Spiegel, which displays and analyzes the results of N body simulations of dense stellar systems. The visualization system allows exploring the simulation by moving through time and space. The extended abstract also discusses interpolation/extrapolation techniques, and data reduction methods, which are used.
