标题： Globular clusters in the Galactic bulge

摘要： 通过球状星团了解银河系bulge（核球）对于深入理解其形成和演化至关重要。 基于动力学特性、轨道、化学丰度和年龄等方面，球状星团与场星属性之间的联系应该有助于揭示不同恒星群体组成部分。 我们根据空间分布和金属丰度定义了一份可能的最佳bulge星团列表，共包含43个条目。 建议未来对新发现的天体（主要来自VVV巡天）进行研究。 这些候选者可能缓解bulge远侧缺失星团的问题。 我们讨论了影响星团到银河系中心距离的消光定律，并得出结论，最合适的总吸收与选择性吸收比值似乎是R$_{\rm V}$=3.2，这与最近的分析结果一致。 提供了bulge星团元素丰度的更新数据。 显示英文摘要

摘要： A view of the Galactic bulge by means of their globular clusters is necessary for a deep understanding of its formation and evolution. Connections between the globular cluster and field star properties in terms of kinematics, orbits, chemical abundances and ages should shed light on different stellar population components. Based on spatial distribution and metallicity, we define a probable best list of bulge clusters, containing 43 entries. Future work on newly discovered objects, mostly from the VVV survey, is suggested. These candidates might alleviate the issue of missing clusters on the far side of the bulge. We discuss the reddening law affecting the cluster distances towards the center of the Galaxy, and conclude that the most suitable total-to-selective absorption value appears to be R$_{\rm V}$=3.2, in agreement with recent analyses. An update of elemental abundances for bulge clusters is provided.
