AST 95-29242 Jane Charlton Dwarf Galaxies and Their Formation: A Study in the Compact Group Environment. Knowledge of the numbers and properties of dwarf galaxies in various environments is an essential element for devising the overall scenario for galaxy formation. The luminosity function of dwarfs is determined by a synthesis of the initial density fluctuation spectrum with evolutionary processes acting to create or destroy existing galaxies. The goal of this observational program is to discover the formation mechanism for dwarf galaxies and to explore the consequences for galaxy formation in general. In particular this program has the following three objectives: (1) To provide the most complete determination of the luminosity function in compact groups, extending well into the regime of the dwarf population; (2) To study the physics of star formation and dwarf galaxy formation in the tidal debris of interacting giants in compact groups; and (3) To determine the overall importance of tidal dwarfs for galaxy formation.

AST 95-29242简·查尔顿（Jane Charlton）矮星系及其形成：紧凑型组环境中的研究。 了解各种环境中矮星系的数量和特性是设计银河形成的整体方案的重要元素。 矮人的亮度函数是由最初密度波动频谱的合成与作用创建或破坏现有星系的进化过程的合成。 该观察计划的目的是发现矮星系的形成机制，并探索一般的星系形成的后果。 特别是该程序具有以下三个目标：（1）在紧凑型组中提供最完整的光度函数的确定，并延伸到矮人人口的状态； （2）研究紧凑型组相互作用巨人的潮汐碎片中恒星形成和矮星系的形成； （3）确定潮汐矮人对星系形成的总体重要性。
