Dr. Merritt, a leading expert on the dynamics of elliptical galaxies, proposes theoretical and numerical studies of the structure and volution of these interesting objects. An algorithm will be developed to determine estimates of the mass distribution of hot stellar systems based on line-of-sight velocity distributions. Models both with and without spherical symmetry will be subjected to numerical and analytical investigation to study their stability and reaction to bending perturbations.

梅里特博士是椭圆星系动力学方面的权威专家，他建议对这些有趣天体的结构和演化进行理论和数值研究。将开发一种算法，以确定基于视距速度分布的热恒星系统质量分布的估计。将对具有和不具有球对称的模型进行数值和解析研究，以研究它们的稳定性和对弯曲扰动的反应。
