Planetary systems around other stars (exoplanets) and their diversity are the highest-profile topic in Galactic astronomy, with broad public interest that further translates into motivation for students to enter STEM fields. The number of known exoplanets has grown to nearly 5000 and may soon grow to a total of 20000 or more. With the UCL-led Ariel’s mission, the European Space Agency aims to take the lead in measuring the composition of a large sample of exoplanets, and the James Webb Space Telescope is also expected to study dozens of planets. In contrast, the characterisation of the stars that host planets or planet-forming disks has received less attention. Spectroscopy of planet- or disk-hosting stars is, however, crucial to the detection and in-depth study of extrasolar planets, including understanding their chemical diversity, and for studying the relation between formation processes and diverse outcomes of star-planet systems. By strengthening the relevant capacities, Europe can be a world-leading region in the study of extrasolar planetary systems while stimulating national-level STEM education and R&D activities. With the EXOHOST Twinning project, we will strengthen the expertise at UTARTU in modern research and management practices, stellar spectroscopic methods and tools, exoplanets, and planet formation. EXOHOST will enable UTARTU to increase its visibility and attractiveness, to implement modern research methods and tools, to become an independent regional leader in exoplanet host star characterisation, and to pose and solve new science questions, leveraging continued partnerships with UU, OEAW, and UCL for future projects, publications, and funding applications. The partner institutions will benefit from strong ties with the UTARTU team for research synergies and new mutual training opportunities

围绕其他恒星（系外行星）的行星系统及其多样性是银河系天文学中最引人注目的话题，广泛的公众兴趣进一步转化为学生进入STEM领域的动力。已知的系外行星数量已经增长到近5000颗，可能很快就会增长到20000颗或更多。通过伦敦大学学院领导的Ariel使命，欧洲航天局的目标是率先测量大样本系外行星的组成，詹姆斯韦伯太空望远镜也有望研究数十颗行星。相比之下，拥有行星或行星形成盘的恒星的特征受到的关注较少。然而，行星或盘状宿主恒星的光谱学对于探测和深入研究太阳系外行星，包括了解其化学多样性，以及研究恒星-行星系统的形成过程和不同结果之间的关系至关重要。通过加强相关能力，欧洲可以成为太阳系外行星系统研究的世界领先地区，同时刺激国家一级的STEM教育和研发活动。通过EXOHOST Twinning项目，我们将加强UTARTU在现代研究和管理实践，恒星光谱方法和工具，系外行星和行星形成方面的专业知识。EXOHOST将使UTARTU能够提高其知名度和吸引力，实施现代研究方法和工具，成为系外行星宿主星星表征的独立区域领导者，并提出和解决新的科学问题，利用与UU，OEAW和UCL的持续合作关系进行未来的项目，出版物和资金申请。合作机构将受益于与UTARTU团队的紧密联系，以实现研究协同效应和新的相互培训机会
