9308005 McMIllan Large-Scale Numerical Simulations of Stellar Systems. Dr. McMillan will continue to develop a new tree-based, high-order integration scheme for the numerical simulation of collisional N-body systems. While a program already in place is now in rudimentary working order, it still lacks most of the features necessary to make it useful for the simulation of real star clusters. The aim now is to complete the code development, perform extensive tests of the program's suitability for stellar- dynamical applications, and begin to apply it to the problem of globular cluster evolution. The result will be a state-of-the-art stellar-dynamical simulation program, and an improved understanding of the mechanisms driving the evolution and appearance of globular star clusters.

小行星9308005 恒星系统的大尺度数值模拟。 McMillan博士将继续开发一种新的基于树的高阶积分方案，用于碰撞N体系统的数值模拟。 虽然一个已经到位的程序现在处于初步的工作状态，但它仍然缺乏大部分必要的功能，使其对模拟真实的星星集群有用。 现在的目标是完成代码开发，对程序在恒星动力学应用中的适用性进行广泛的测试，并开始将其应用于球状星团演化问题。 其结果将是一个最先进的恒星动力学模拟程序，并提高对驱动球状星星团演化和出现的机制的理解。
