We are pleased to announce the SUBSTELLAR ASTROPHYSICS 2026 international conference to be held in the week 10-14 August near the historic town of Tordesillas, Castilla, Spain.

This conference will bring together researchers interested in Substellar science with special emphasis on exploiting the wealth of data provided by ESA Euclid Space mission complemented with other surveys and follow-up observations.

Substellar science has emerged in the last few decades as a new branch of Astrophysics that connects Stars, Exoplanets and the Solar System. The advent of new surveys such as Euclid, Nancy Green Roman Space Telescope 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.

A total eclipse of the Sun will take place during the conference (August 12, 2026).
