Descrizione del progetto
Migliorare l’eccellenza estone nello studio delle stelle che ospitano pianeti
La ricerca di pianeti orbitanti intorno ad altre stelle (esopianeti), la previsione della loro composizione e del loro numero nell’universo, nonché lo studio della loro formazione e del possibile sviluppo della vita su di essi sono tra i temi più affascinanti dell’astronomia galattica. Secondo quanto riportato dalla NASA, nella nostra galassia il numero di esopianeti accertati ha superato i 5 000. Per stabilire la composizione degli esopianeti rocciosi, gli astronomi utilizzano tecniche indirette, che possono rivelare molte informazioni sulle condizioni fisiche di questi mondi. Tuttavia, meno attenzione è stata rivolta alla caratterizzazione delle stelle che li ospitano. Il progetto EXOHOST, finanziato dall’UE, permetterà all’Università di Tartu in Estonia di aumentare la propria visibilità, di applicare metodi e strumenti di ricerca moderni e di diventare un ateneo leader nella regione nell’ambito della caratterizzazione delle stelle che ospitano esopianeti.
Obiettivo
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 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.
