Since 2013 astronomers from Hamburg Observatory and the Universidad de Guanajuato have together been operating the TIGRE facility, a robotic and spectroscopic telescope dedicated to the study of long-term monitoring of various types of stars, working in close collaboration with theoretical experts for atmospheric modeling and evolution models. The collaboration between the two institutes has been extremely fruitful and has already resulted in a variety of publications in a variety of different fields in astrophysics. In response to the call for proposals issued by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) and the Mexican National Council for Science and Technology (CONACYT) in July 2016 to fund joint German-Mexican research projects we seek financial support to continue our successful German-Mexican collaboration. We specifically ask for support for travel and publication costs in our endeavor to tackle the following scientific issues:Chromospheric activity level and rotation periods: Beyond the Mount Wilson sampleStellar activity periods and dynamo modes across the HRDStellar activity properties of giantsStatistical analysis of time domain dataExtremely high-resolution spectroscopy of target starsQuantitative diagnostics of TIGRE targets by PHOENIX and evolution modelsBinary stars with phase dependent phenomena and exotic objects

自 2013 年以来，汉堡天文台和瓜纳华托大学的天文学家一直在共同运营 TIGRE 设施，这是一台机器人和光谱望远镜，致力于研究长期监测各种类型的恒星，与大气建模和观测的理论专家密切合作。进化模型。两个研究所之间的合作非常富有成效，并已在天体物理学各个不同领域发表了各种出版物。为了响应 Deutsche Forschungsgemeinschaft（DFG，德国研究基金会）和墨西哥国家科学技术委员会 (CONACYT) 于 2016 年 7 月发出的资助德国-墨西哥联合研究项目的提案，我们寻求财政支持，以继续我们的成功德国与墨西哥的合作。我们特别请求支持我们努力解决以下科学问题的旅行和出版费用：色层活动水平和自转周期：威尔逊山样本之外的恒星活动周期和跨HRD的发电机模式巨星的恒星活动特性时域数据的统计分析极高-目标恒星的分辨率光谱PHOENIX 和演化模型对 TIGRE 目标进行定量诊断具有相位相关现象和奇异物体的双星
