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

[357387 . Bailyn] PI将在致密双星和球状星团领域进行研究。紧凑型双星是由白矮星、中子星或黑洞组成的系统。通常伴星的质量被转移到致密的天体上，产生各种各样的能量现象。PI计划在不同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的强引力场中独特的物理现象。虽然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将研究这些天体，目的是了解星团的动力学和星团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. ***
