Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

EXOWORLD addresses the urgent scientific need to understand the formation, evolution, and conditions for planet habitability beyond our Solar System. Despite the discovery of thousands of exoplanets, most remain poorly characterised, limiting our ability to interpret their diversity and place our own Solar System into context. The project brings together an international and interdisciplinary network to develop innovative techniques for the detection, characterisation of exoplanet properties, and statistical analysis of planet populations. By training early-career researchers, exploiting cutting-edge space- and ground-based data, and applying novel methods such as machine learning, EXOWORLD will strengthen the foundation for Europe’s leadership in exoplanet science. Its results will help bridge knowledge gaps in planetary system evolution, and strengthen Europe’s capacity to benefit scientifically from missions such as JWST, PLATO, and ARIEL, delivering long-term impact at both scientific and societal levels.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

As part of the project, EXOWORLD used custom pipelines to detect exoplanet candidates from transit surveys, some of which were subjected to follow-up observation campaigns for in-depth characterisation, including the determination of their masses, radii, bulk compositions, projected stellar obliquities (via Rossiter-McLaughlin effect), and atmospheric characterisation (via transmission spectroscopy). The consortium developed machine learning tools to advance transit (and soon also radial velocity) detection methods to improve efficiency of detecting planetary signals. Furthermore, EXOWORLD supported the commissioning of the new radial velocity instrument, PLATOSpec, which will be used to support the high precision radial velocity measurement of exoplanets in the PLATO era. The project also studies exoplanet populations and provides insights on the correlation between planet and host star properties. Collectively, these accomplishments provide a more comprehensive understanding of exoplanet diversity and enhanced Europe’s readiness to exploit data from future space missions such as PLATO.

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

EXOWORLD has advanced exoplanet science by developing machine-learning algorithms that improve the efficiency of planet detection and enable the identification of small planetary signals, including monotransits. The project has also conducted in-depth characterisation of both new and known exoplanets, providing precise measurements of their masses, radii, densities, and orbital properties. Selected exoplanets also underwent follow-up atmospheric characterisation. These well-characterised planets provide a robust foundation for studying planet population statistics, allowing researchers to identify correlations between planetary and stellar properties. Such insights place powerful constraints on planet formation and evolution theories, helping to identify the mechanisms that are responsible for the diversity of exoplanet systems. To ensure further uptake, continued development of high-precision instrumentation (such as PLATOSpec), advanced data-processing and modelling capabilities, and interdisciplinary research collaborations will be essential, alongside the creation of software and analysis tools, adoption of open-science practices, and training of early-career researchers. These steps will maximise the long-term scientific impact of EXOWORLD’s advances and reinforce Europe’s forefront role in exoplanet research.
