BROWN DWARFS KEEP THEIR COOL: 30 YEARS OF SUBSTELLAR SCIENCE, La Gomera, 1-5 September 2025
Fifty years ago the search for the first Brown Dwarf (BD) was raging among various teams over the world. After several years of intense studies, in September 1995 the first BD were announced in the Pleiades cluster and as a companion to the bright star Gl229, starting a new era in astrophysics.
Since then, the field has grown significantly with thousands of BDs known with different spectral types, ages, and metallicities. However the first truly unambiguous halo BD remain to be identified.
Do they exist? How formation processes of substellar objects differ with metallicity?
Representatives from the SUBSTELLAR project formed part of the Scientific and Local Organising Committees, and some of them attended the conference and presented the status of their research works:
Eduardo Martín: Brown Dwarfs with the Euclid Space Mission (presented by M. Zerjal)
Marusa Zerjal: Photometric Ultracool Dwarf Catalogue in Euclid's Q1 Data Release
Styliani Tsilia: Probing the Ultracool Dwarf Population Around the Horsehead Nebula
Nafise Sedighi: Unveiling Ultracool Dwarfs with Euclid and ATMO
Jun-Yan Zhang: Detection of Methane and Metallicity Constraints on the Nearest Extreme T Subdwarf
Sara Muñoz Torres: Characterizing the First Field Brown Dwarf Binary Discovered with Euclid
