球状星团天文学在地面设施上的未来机会
Future Opportunities for Globular Cluster Astronomy at Ground Based Facilities
摘要:
尽管在过去的$\sim 10$年里取得了很大的进展,特别是由于HST,一些令人兴奋的开放问题仍然困扰着天文学家在我们自己和其他星系的球状星团工作。这些问题包括确定更准确的年龄以评估大质量黑洞是否隐藏在某些星团的中心,从确定红巨星风的物理起源以评估星团结构和动力学是否对单个星团恒星的演化产生影响,从证明一些星团是否拥有自己的暗物质晕,到最终了解球状星团的形成,星系形成的背景等等。在这篇评论中,我简要地概述了地面望远镜及其仪器如何帮助解决这些问题,通过本十年,2001-2010年。还对下一个十年进行了展望。
英文摘要:
In spite of great progress over the last $\sim 10$ years, especially thanks to HST, a number of exciting open problem still puzzle astronomers working on globular clusters in our own and other galaxies. These problems range from determining more accurate ages to assess whether massive black holes hide at the center of some clusters, from identifying the physical origin of red giant winds to assess whether there is an influence of cluster structure and dynamics on the evolution of individual cluster stars, from demonstrating whether or not some clusters possess a dark matter halo on their own to eventually understand the formation of globular clusters in the context of galaxy formation, and more. In this review, I briefly sketch how ground based telescopes and their instrumentation can help solving these problems through the present decade, 2001-2010. A glimpse to the next decade is also given.
