Descripción del proyecto
Mejorar la excelencia de Estonia en el estudio de estrellas que albergan planetas
La búsqueda de planetas en órbita alrededor de otras estrellas (exoplanetas), la predicción de su composición y abundancia, así como la comprensión de cómo se forman y cómo puede desarrollarse la vida son algunos de los temas más apasionantes de la astronomía galáctica. Según las cifras de la NASA, el recuento de exoplanetas confirmados en nuestra galaxia ha superado los cinco mil. Los astrónomos utilizan técnicas indirectas para determinar la composición de los exoplanetas rocosos, lo cual puede revelar mucha información sobre las condiciones físicas de estos mundos. Sin embargo, se ha prestado menos atención a la caracterización de las estrellas que albergan estos planetas. El equipo del proyecto EXOHOST, financiado con fondos europeos, permitirá a la Universidad de Tartu (Estonia) aumentar su visibilidad, aplicar métodos y herramientas de investigación modernos y convertirse en líder regional independiente en la caracterización de estrellas que albergan exoplanetas.
Objetivo
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.
