EXOHOST is a Twinning project that will develop excellence in the research of exoplanets and their host stars at UT Tartu Observatory. Our partners are University College London (UCL), Uppsala University (UU), and Space Research Institute of the Austrian Academy of Sciences (OEAW).

Exoplanets and their host stars are one of the most actual topics in 21st-century astronomy. Spectroscopy of exoplanet host stars is important to thoroughly research planets outside of the solar system, understand their chemical diversity and study the processes that lead to the formation of new planetary systems. This research can answer questions about life elsewhere. Scientific data collected during this project will be publicly accessible. In addition, the activities and results of the project will be introduced to the general public in popular science publications and various media outlets.

This project has received funding from the European Union’s Horizon Europe research and innovation programme under grant agreement No. 101079231 (EXOHOST), and from UK Research and Innovation (UKRI) under the UK government’s Horizon Europe funding guarantee (grant number 10051045). The budget for this project is 1 498 931 €. The project will run for 3 years (until December 31st, 2025).
