SUBSTELLAR ASTROPHYSICS
Substellar science has emerged in the last few decades as new branch of Astrophysics that connects Stars, Exoplanets and the Solar System. The advent of new surveys such as Euclid and Rubin LSST is poised to increase the numbers of known substellar objects by more than an order of magnitude, while the James Webb Telescope is providing new details about their properties. Rapid advances in observational capabilities have spurred the development of a new generation of theoretical models, now reaching unprecedented levels of accuracy and physical completeness.
This meeting will bring together researchers interested in Substellar science with special emphasis on exploiting the wealth of data provided by Euclid and complementing it with other surveys and follow-up observations.
The conference is supported by the European Research Council Advanced grant nicknamed Substellar.
A total eclipse of the Sun will take place during the conference (August 12, 2026).
The proceedings of the conference will be formally published as part of the conference series of Astronomische Nachrichten.
