本文总结 Cool Stars 23 分会场关于开放星团作为冷恒星演化实验室的讨论，涵盖自转、磁活动和化学丰度演化主题，并展望新巡天与任务带来的未来研究方向。
AI 中文摘要
开放星团仍然是校准基本恒星属性（如自转、磁活动、表面化学和内部结构）在前主序到主序及主序后恒星寿命期间如何演化的最强大实验室之一。由于星团成员共享相同的年龄、银河系环境和初始成分，它们为陀螺年代学、活动-年龄关系和化学时钟等年龄测定技术提供了经验锚点。本文总结了于2026年6月15日在日本东京举行的 Cool Stars 23 分会场——开放星团作为冷恒星演化的实验室。该分会场包括一场特邀综述报告、十场贡献演讲和十场海报快闪展示，围绕三个主题组织：自转演化、磁活动和化学丰度（锂消耗、[C/N]、[Y/Mg] 和中子俘获元素）。我们最后总结了小组讨论中确定的开放问题，以及新巡天（如 Gaia DR4、4MOST、WEAVE）和任务（如 PLATO、Roman）将在未来几年推动的观测和理论工作。这些努力将共同帮助评估该领域的当前状态并塑造其未来方向。
英文摘要
Open clusters remain among the most powerful laboratories for calibrating how fundamental stellar properties such as rotation, magnetic activity, surface chemistry, and internal structure evolve over the pre-main-sequence to main-sequence and post-main-sequence stellar lifetime. Because cluster members share a common age, galactic environment, and initial composition, they provide empirical anchors upon which age-dating techniques such as gyrochronology, activity-age relations, and chemical clocks are built. This paper summarizes the Cool Stars 23 splinter session - Open Clusters as Laboratories for Cool Star Evolution, held on 15 June 2026 in Tokyo, Japan. The session comprised one invited review, ten contributed talks, and ten poster pop-up presentations, organized around three themes: the evolution of rotation, magnetic activity, and chemical abundances (Li-depletion, [C/N], [Y/Mg], and neutron-capture elements). We close with a summary of the open questions identified in the panel discussion and the observational and theoretical work that new surveys (e.g. Gaia DR4, 4MOST, WEAVE) and missions (e.g. PLATO, Roman) will enable over the coming years. Together, these efforts will help assess the current state of the field and shape its future directions.
