9357387 Bailyn The PI will pursue research in the areas of compact binary stars and globular star clusters. Compact binary stars are systems in which one component is a white dwarf, neutron star or black hole. Often mass from the companion is transferred to the compact object producing a variety of energetic phenomena. The PI plans to observe these systems at a variety of wavelengths to establish their properties. They can then be exploited to learn about unique physical phenomena in the intense gravitational field of the compact object. Although most of the stars in globular clusters are explained by the theory of stellar evolution, a small minority have unexpected characteristics. These anomalous objects are thought to be the result of binary star evolution or stellar collisions. The PI will investigate such objects with the goal of understanding the relationship between the dynamics of the clusters and the evolution of the stars in them. ***

9357387 Bailyn 首席研究员将在致密双星和球状星团领域进行研究。 致密双星是其中一个组成部分是白矮星、中子星或黑洞的系统。 通常，来自伴星的质量会转移到致密物体上，从而产生各种能量现象。 PI 计划在各种波长下观察这些系统以确定其特性。 然后可以利用它们来了解致密物体的强引力场中的独特物理现象。 尽管球状星团中的大多数恒星都可以用恒星演化理论来解释，但也有少数恒星具有意想不到的特征。 这些异常物体被认为是双星演化或恒星碰撞的结果。 PI 将研究这些天体，目的是了解星团动力学与星团中恒星演化之间的关系。 ***
