NSF Young Investigator: Compact Binary Stars and Anomalous Stars in Globular Clusters

9357387白莲派将在致密双星和球状星团领域进行研究。致密双星是指其中一个成分是白矮星、中子星或黑洞的系统。通常情况下，来自伴星的质量被转移到致密物体上，产生各种能量现象。PI计划在不同的波长下观察这些系统，以确定它们的性质。然后可以利用它们来了解致密物体强烈引力场中的独特物理现象。虽然球状星团中的大多数恒星都是用恒星演化理论来解释的，但也有一小部分具有意想不到的特征。这些异常天体被认为是双星演化或恒星碰撞的结果。PI将调查这类天体，目的是了解星系团的动力学和其中恒星的演化之间的关系。***

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. ***
