Dr. Cudworth, at the Yerkes Observatory of the University of Chicago, is conducting research on star clusters which primarily involves observational investigations of proper motions and photometric studies of the members of globular and open clusters. Star clusters are important for testing theories of stellar evolution, galactic evolution, and stellar dynamics. Clusters also contribute to the luminosity calibration for a variety of types of stars, as well as the distance scale of the Galaxy and the Universe. In all of these areas a criterion for membership of stars in the cluster is needed which is independent of theories of stellar evolution. Measurements of proper motions are used to derive cluster membership, study the internal dynamics of the clusters, and derive the cluster space velocities. Dr. Cudworth has a reputation for careful and accurate contributions in this area of fundamental astronomy.

芝加哥大学Yerkes观测值的Cudworth博士正在对星团进行研究，该研究主要涉及对球形和开放群体成员的适当运动和光度研究的观察研究。 星团对于测试恒星进化，银河进化和恒星动力学的理论很重要。 簇还有助于各种恒星以及银河系和宇宙的距离尺度的光度校准。 在所有这些领域，需要在集群中恒星成员的标准，这与恒星进化的理论无关。 适当动作的测量用于得出集群成员身份，研究簇的内部动力学并得出群集空间速度。 Cudworth博士因在这一基本天文学领域的仔细而准确的贡献而闻名。
